Acer Aspire One D255

One of the basic Acer philosophy to stay ahead is presents the latest technology, and they showed it again this time. Shortly after Intel announced the Atom N550, Acer Aspire One D255 immediate release based on these processors. Currently you can get these notebooks in the market with price Rp3 juta (Linux) and Rp3,7 juta (Windows 7 Starter plus Android). Yup, the price is not to much different from the N450-based notebook.

By design, the Acer aspire One D255 has a design similar to the previous generation. Just look at its sleek and slim, with less than 1 inch thick (in the open state). It becomes its own record because the larger TDP Atom N550 should make cooling systems Acer D255 more complicated, which led to the design more bigger. Moreover, this notebook uses battery size 6-cell (4400mAh, 49Wh). But it turns out Acer managed to design this notebook with a slim design and weighs only 1.15 kg.

Talk about battery, my attention focused on durability in battery mode. With the TDP processors larger, i expect this notebook battery life will be under N450 Atom based notebook. On testing a video mode (where i play HD video on an ongoing basis), our expectation was proven. Acer D255, only lasted 3 hours 43 minutes, losing out to HP Mininote 210 (4 hours 29 minutes). But in the test Battery Eater Text Mode (running text continuous), Acer D255 managed to achieve 8 hours more, longer than the HP Mininote 210.

From these results, it can be concluded that Acer D255 battery duration will be seen in heavy applications. However, in lightweight applications, Acer D255 retains the image of a durable notebook.

Benefits of Dual Core
Then, what effect the presence of dual core in terms of performance? As a first approximation, the existence of dual core would be clearly visible on the multi-tasking applications such as Sysmark 2007. For the testing using a variety of applications (Adobe Photoshop, Adobe Premiere, and Flash) that run together, Acer D255 performance seen more quickly.

The benefits of dual cores is also seen in the test video encoding using Microsoft Expression Encoder application. The application supports multithread (one application can be done along the entire core), so the result an increase of more than 40%.

However, in applications such as single-thread Encoder DBPower (for encoding audio), it become slower. But in the test video mode, Acer D255 successfully play 720p video smoothly. There is still a little jerky, but much smoother than the Atom N450-based notebook.

Features
In facilities, Acer D255 is relatively not much different from other notebooks. Around his perch USB 2.0 (3 pieces), Ethernet, memory slot, and VGA-Out. While on the wireless connection, this notebook equipped with WiFi without Bluetooth.

But there is a unique facility in this notebook, the Android. Yes, a special operating system smartphone had actually been invested on this notebook. Its function as an operating system backup if you're lazy go to Windows 7 Starter Edition, you will find a standard computing applications, ranging from the browser, chat, until the email client.

To get into Android, the duration is only about 10 seconds. After that, you will be faced with the look like Android in the smartphone, complete with a row of menu applications. Android was not difficult to find a WiFi network in my office, as well as with the flash.

Still, there are some things that quite disturbing. First, the Acer does not provide a special key to get into Android. So, i still have to push the Power button. Problem is, when it wanted to go to Windows 7, i have to press F9 when StartUp. If not forget, the system will go into the Android, and count down of 10 seconds (or you can set it). If you do not press any button, new information systems into Windows 7. In our opinion this procedure is somewhat inconvenient, as it requires special attention and time to go into Windows 7. Why not, there are two special keys to get into Android and the Windows 7, so it is more practical.

I also do not see any Android Market in the application window. Though, Android Market will allow us to get additional applications. Consequently although interesting, the existence of Android on the Aspire One D255 is felt less than the maximum.

Conclusion
If filled to the test results, see if Atom N550 will be very beneficial if you often do multitasking or running an application that supports multithread. In these conditions, improved performance which can occur up to 40%. While the application singlethread, speeds become slower that will make its performance remains about 10%.

Based on these facts, i think Atom N550 quite refreshing notebook market. The majority of user do many things simultaneously, listening to music as surf the internet, so Atomic of dual core presence to the character. Another fact is the existence of extra core does not make this processor-intensive power, reflected in the performance of these notebooks are still able to stand up to 8 hours.

Excess Atom N550 is sweet chime on Acer Aspire One D255. Despite offers performance, and good battery life, this notebook designs remain lean and thin. The price was not too far compared to previous generation notebooks. So if you're currently looking for a notebook, the Acer Aspire One D255 is an option which must be signed in the first list.
 
In multitasking scenario (Sysmark 2007) or application that supports multithread (video encoding), the performance of Acer Aspire One D255 can be more hurried up to 40%. However, in applications singlethread (audio encoding and 3DMark 2006), slightly lagging the performance of Acer.

Stay Thin
Although using more processors, Äúpanas, Äù, Acer Aspire One still managed to design a D255 with a slim and sleek design.

Design Chiclet
In this D255 Acer Aspire One re-use chiclet design as the previous generation. The design makes typing process to be comfortable while i expect that the repulsion is more steady.

Size Large
This small-sized battery was a 6-cell type, and can last up to 7 hours when used in running text.

Plus: good performance; to play HD video smoothly; thin design; equipped Android.

Minus: The price is slightly more expensive; without Bluetooth.
