In 2009, the PC market, the cottage the Internet has gone from crazy to the collapse of the process, but this is not the collapse of the brand online, in fact, Internet PC market, this is still the main growth driver. Data show that Internet sales of shares in this account more than 20% of all notebooks. In 2009 the Internet this year shipments are expected Acer Aspire 8920G battery to more than 35 million units.

Since its inception in 2007, Internet awareness of this product have soared, and ultimately usher in cottage manufacturers to enter. In the second half of 2008, the Internet can be said to have entered the peak period, almost all of the industry’s leading PC is often involved in this area. In fact, the Internet for PC manufacturers to bring the good sales figures, which the financial crisis become more important.

After the peak must be dropped. A lower technical threshold sparked a cottage blind entry, price competition also entered the disordered state, plummeted from 4,000 yuan, the brand was down to 1999 yuan in this online. Some cottage even play below the price of 1,000 yuan. Acer Aspire 6920 battery
Consequences of the Internet in this market is rapidly shrinking profit margins.

From the product itself, the Internet location of this feature is not entirely a notebook, is the second PC. However, when the manufacturers the publicity did not emphasize this point, many for the first time the user has chosen to buy notebooks online book, that can be used to office entertainment. Results are very disappointing, Internet this fact can not do anything. Narrow version of the keyboard and the screen is difficult to adapt to other users. The performance is even more out of the question, the Internet can only be used in this fact, browsing the web, view email, chat, Acer Aspire 8920 battery in order to film the game is impossible.

External disorder lack of competition and the product itself led to the Internet in mid-2009 to enter in this short period of confusion. The most affected cottage manufacturer, have closed down or restructuring. Internet brands are cool-headed thinking of this in their own development, the frequency of introduction of new products began to slow down and focus on the quality of the product itself, and personalization. In fact, this is also the Internet should have some trends.

In the first quarter of 2010, Intel will continue to release new access to this platform, access to this market will enter a new stage of development. The idea that the Internet prior to the annual decline in 2010, and even the “Internet of this,” a title will disappear. Another view is that the Internet this would still have to grow rapidly. From the current market analysis, access to the Internet next year, this market does not like the last year or this year’s ups and downs, but will continue to advance in the steady.

Outlook 6: Touch & 3D & Games Video of the

Expectations index: ★ ★

Touch screen and 3D technology in the application of computers has begun to show a new development trend, Acer Aspire 7720G battery integrated computer and notebook computers has been achieved on both touch-screen operation, the only lacking is the technology itself optimization and application follow-up.

3D technology, we can see that NVIDIA launched a 3D three-dimensional magic mirror technology, AMD will also be in January 2010 publication of the CES trade show related technology programs. Currently, Acer and Asus have launched to support 3D technology, notebook computers, will experience by wearing glasses. Touch screen and 3D technology in the future of computer games and entertainment will play an increasingly important role, and can further deepen the human-computer interaction experience.

Entertainment video games in 2009 high-end notebook actually do not imagine hot, the financial impact of the crisis is one of the reasons that consumers purchase notebook to be more careful calculations, is no longer simply the pursuit of high distribution. Another reason is the concern that the market itself is limited.

But the video game market is still the high-end notebooks have their own market space in 2010 will continue to grow, but the overall look is still maintained at a stable level, there will be no ups and downs. The data provided in our ZDC, there are nearly 10% of users expressed concern about the market. High-end gaming notebook market share Acer Aspire 7720Z battery of audio and video in fact very much related to the standard of living in the out of the financial crisis, after the market in 2010 there may be a new development.

Outlook 7: Tablet PC & Other

Expectations index: ★

Tablet

Tablet PCs are expected to start in 2010 into the first year of development, the biggest driving factor is the apple, in addition to Dell, ASUS, HP and other vendors want to push flat-panel product rumors. From another perspective, Tablet PC may be towards the development of multimedia applications, such as e-books. In fact, e-book can be seen as a form of tablet PCs, but highlighted the function of reading digital books. In addition, the Tablet PC there will be many more applications, but all the development needs of technology and application support, perhaps next year will be the first year of the Tablet PC.

Windows 7

Many people think that Windows 7 prior to the promotion of PC market growth will become a major factor, and in the latter half of 2010 revealed. In fact, in promoting the role of Windows 7 is a necessity, because it solves some of the problems left over Vista, according to the natural order of product development, Windows 7 will naturally be gradually replaced by Vista (now hard to completely replace XP), will be on the PC play a role in promoting market growth.

Summary

PC industry in the past few years an alarming pace of development, in particular the decline of the price. A few million have been stepped down computer products, PC products began to be classified as a kind of consumer goods, the future will be further differentiated, as well as personalized design evolution. On the whole, mainstream notebook PCs will continue moving in the performance of the two direction thin fuselage, and occupy a larger market share; desktop computer will still occupy a certain market share, one desktop computer is the development of another a form; the Internet this will be to maintain a certain market share, in the steady advance.

To explore in this article are only visible point of PC market growth, there are products with technical highlights. From this year’s market point of view, perhaps next year’s PC market, there will be a new growth point of the outbreak, as well as the year before this year’s Internet this CULV.

Looking ahead: Core Duo processor i3/i5/i7

Expectations index: ★ ★ ★ ★ ☆

In September of this year’s Intel Developer Forum IDF, on the new architecture based on the mobile version of Nehalem Core i7 processors to meet formally with you. The industry’s major PC makers also have a positive response followed by the introduction of configuration i7 quad-core processor notebooks. Acer Aspire 5720G battery Currently on the market already has Alienware, Shenzhou, ASUS, Lenovo and Asus and other vendors of products, of which 6999 yuan’s Shenzhou sought after by many big A, quad-core notebook lethal evident.

The first announced quad-core processor, Core i7 using 45nm technology, including those for mainstream notebook Core i7-720QM, i7-820QM-oriented high-performance gaming notebook Core i7-920XM.

In 2010, Intel will release the next generation of R & D, code-named “Arrandale” mobile processors, including Core i3, i5, and i7 series.Acer Aspire 6920G battery In fact, Intel in the future will be the main push “Core (Core)” brand. In other words, the future of the notebook, the Core i3, i5, and i7 will cover a variety of price segment, will also become the basis for the notebook market growth.

Arrandale next release quad-core mobile processor integrated CPU and graphics processing functions, using 32-nanometer manufacturing process as well as the second-generation high-K metal gate transistors. The Arrandale processor will be equipped with a 32nm architecture of Westmere display CPU and Acer Aspire 7520G-502G25Mi battery a 45nm Core and North Bridge controller ICs.

Has released the mobile version of Core i7 processors with Core-frequency acceleration technology, Hyper-Threading Technology, up 3 8MB cache, integrated memory controller, built-in SSE4.2 instruction set and many other technological advantages. Evaluation data, and compared to the previous quad-core processor, i7 quad-core processor performance than previous Intel’s Q9000 series quad-core processors out of a lot stronger.

Can be expected is that the notebook market next year, will enter “i” times, whether it is 3D gaming audio-visual entertainment, or personality style, or a mobile office, will have “i” presence.

Prospect 3: CULV thin in this

Expectations index: ★ ★ ★ ★

CULV thin and light notebook market in 2009 has won a lot of attention is Acer Aspire 5910G battery on the market this year, one of the few bright spots. With the ultra low voltage Intel i5, i7 release of new processors, CULV platform, the performance of thin and light notebooks will also be further enhanced.

CULV notebooks are thin and light, portable, long battery life features. CULV generally control the weight of the notebook 2 kg within easy life can be 6-8 hours, some products can reach 10-12 hours.

On the other hand, CULV there is still thin and light notebook is slightly lower performance, the game can not satisfy the entertainment demands. However, the reason was able to CULV popular not because of performance, if the properties of stem Mody asked not to buy the mainstream dual-core alone has displayed in this?

May be other hand, is always hope that all the needs of the user can achieve the same product, at the same time will naturally be thin to meet the required performance. As already mentioned, with the release of the performance i5 processor, CULV thin and light notebook is bound to improve performance after use. In addition, CULV notebook to join one of the graphics card is also a trend, in fact, this year’s CULV related products have been on the market. In 2010, the market may appear more noticeable CULV thin in this unique mix of uses, which will Acer Aspire D150 battery become one of the factors attracting users.

From the use of point of view, the accelerated pace as society need to carry laptop users who travel extensively, more and more of the lightweight nature of these users will naturally be very high demands on the battery time to time and overall performance requirements are not reduced.

Prices, this year the mainstream notebook CULV in between 4,000 yuan to 7,000 yuan next year also there will be no major changes.

On the other hand, there are a lot of people are worried, CULV access to this notebook will step behind in the dust, there are a number of emerging brands or cottage manufacturers have begun to set foot CULV thin book, some people worry that the market would be do “stinky.” In fact, this concern is dispensable, because the key to look at the upstream chip manufacturers, as long as Intel and PC makers can be a good control over big, CULV market still has very good prospects.

It can be expected that next year’s CULV thin this will be more intense competition in the market, Intel released a new generation of low-voltage processors in the overall performance, power and endurance to continue to meet the needs of users, thin upper further enhanced. In addition, AMD has also greatly push the Neo low-voltage processors, the same face is thin and light notebook market, so next year will be more intense competition in the market, the outlook is no doubt that there are PC makers say, CULV thin and light notebooks have Acer Aspire 8930 battery occupied the notebook out of a total cargo share of 30 percent next year, this figure would be even higher.

Looking 4: One Computer

Expectations index: ★ ★ ★ ☆

One computer is not a new type of PC, but only a new type of PC, but not until the second half of 2008, the market is really concerned about being PC manufacturers, and some pick up in 2009.

ZDC provides the number of shows in 2008, only one or two PC vendors have introduced integrated computer products, but in the second quarter of 2009, the introduction of integrated manufacturer of computer products has reached 17, the fourth quarter of 2009, has reached 19, including Lenovo, Apple, Shenzhou, HP, Dell, Founder, Acer aspire 9500 battery Sony, Haier brand. The market in 2010 to launch the number one computer PC makers may not be substantial growth, as almost all manufacturers have now begun to move into this area. However, the number of products on one computer will be large-scale development.

From the number of products show that, in July 2008, the market only about 40 variety. By the fourth quarter of 2009, the market has been the number one PC over 100 models, is three to four times a year ago. This also shows more and more companies to follow up this market.

Concerned about the degree of respect, from July 2008 to the present, one concern has been on the computer on the rise. One computer users have a better understanding of have begun.

Speaking of users, one computer’s current location is mainly for the young and trendy high-end users, this part of the user is Acer Aspire 5920 battery also relatively higher incomes, such as private entrepreneurs, corporate owners, the pursuit of personal fashion young users.

In fact, apart from this part of the user, one computer there to open up a larger market. Educational and government agencies is the potential market, many government and educational institutions are currently still using the old desktop machine, because who is not willing to take the initiative to replace the peace Cou can use. If the PC makers to enter this market, there must be new discoveries.

On the other hand, one can actually facing the computer game market, game computer users do not consider buying one because of its lack of expandability, they still prefer to mix themselves with better performance of accessories to achieve satisfactory results. So for this part is used for the provision of adequate performance as long as the problem can be solved. In fact, PC makers have already launched a high-end gaming PCs together.

In addition, we even think that one computer in the rural market has great potential to one computer as a dowry is a good idea. In fact, some manufacturers have already put into action.

Future prospects of integrating the computer is owned character of its own decision. One computer integrated host configuration, on the whole is only a display. The benefits of this design is a small footprint, no longer have many data lines wound. From the exterior point of view, an integrated computer design fashion simple, integrated desktop computers are better than good-looking appearance. From the application point of view, one in fact to have an ordinary desktop computers owned by all of the functions, applications and more convenient operation.

The existing main problem is price, another one computer user awareness is not enough. Overall, with the development of related technologies, integrated computer next year, will further reduce the price of the product performance and design will be further enhanced.

An international PC makers head home computer even said that one computer in 2010 it is expected to have split the desktop world, but in the long run, one computer may eventually become a traditional desktop’s demise.

Outlook 5: Internet access in this
