The Netbook comes with an Android operating system, ASUS G50V-A2 Battery which can be booted to instead of Windows. The advantages: The smart phone OS is loaded within seconds, only requires few system resources, and is hence economical. It contains a web browser (Firefox), Google Webmail, Google Talk, and a calendar. For those that want to quickly access information, Android could possibly lend a helping hand. Practically we couldn't imagine that anyone will use this feature though. From standby the familiar Windows 7 Starter is also loaded within seconds.Acer provides a 1 year warranty, including 1 years International Travellers Warranty (ITW). ASUS G50V-AK062G Battery
Acer's FineTip keyboard has a short travel, an unclear pressure point, and a firm (right) to spongy (left) end stop. The keys only have a small gap between each other. The key markings on the F and J keys can be felt clearly. Typical for a Netbook are the small arrow keys including page up and down buttons. Attempting to quickly use these for navigation could lead to pressing the wrong button.ASUS G50V-AK118J Battery
Another flaw when typing on the One D255 is the narrow palm resting area. Big hands will overhang the edge and slip over the hard corner. Altogether the typing feeling is short winded (short travel), and without good feedback (partially spongy end stop). ASUS G50V-AS067C Battery
The multi-touchpad (V7.2) surface is homogeneous with the palm resting area. Two tiny haptical raised lines separate the touch sensitive area on the left and right sides. The touchpad has the same smooth haptics as the surrounding palm resting area. The Synaptics touchpad offers many settings for customization. For example when not wanting to turn pages or scroll, this feature can simply be disabled.ASUS G50V-EP048C Battery
The not optically marked horizontal and vertical scroll bars have to be activated in order to scroll through websites or documents. The surface of the touchpad appears sufficiently large. It is sensitive right up to the edges. The buttons have a short travel and make a muffled clicking sound. The smooth surface is soft and can easily be distinguished from the rest of the touchpad.

The 10.1 inch display (25.6 centimeters) has a resolution of only 1024 x 600 pixels (WSVGA). HD-Ready (1366 x 768) would likely be more favorable for some users since this allows for better oversight on the desktop, and would also allow more practical working with several windows at the same time. The display is exactly the same as that on the One 521.ASUS G50V-EX129C Battery
The contrast of the AUO panel (B101AW06 V1) is, ASUS G50V-P8600 Battery as is so often the case, bad: 195:1. Contrast describes the white content in black colors. Colors only appear half way brilliant due to the glare-type AUO-TFT. The glare characteristics enhance the optical appearance of colors. The color space couldn't be measured by us, since the software for our Colorimeter is not compatible with the WSVGA resolution. Spectacular results would not have been expected though. ASUS G50V-X1 Battery
Acer touts a High-Brightness (200-nit) display. Nit stands for Candela per square meter (cd/m²), which is why our measurements of on average 183 cd/m² do not correlate with Acer's claims. Merely in the upper right corner about 204 nit are reached. The illumination is just about even (81 percent), so that we could not recognize any lighter areas on a completely black display.ASUS G50V-X2 Battery
For the color representation the glare type display is not the worst choice, but under direct sunlight it is a bit of a catastrophe. Trees, houses, garden chairs, and users are mirrored. The luminance of 183 cd/m² cannot trump the reflections. In order to achieve acceptable viewing scenarios, users have to either find a place indoors or in the shade. ASUS G50V-X5 Battery
In the sun the surface of the shiny display frame makes itself noticeable in a negative way. Finest dust particles accumulate there as well as on the display surface. The provided polishing cloth thus becomes the weapon of choice against finger prints and dust.ASUS G50VM Battery
View front, thick cloud cover, reflectionThe horizontal viewing angles are just about acceptable. At up to about 40 degrees deviation from the center we were able to read writing clearly, and the inversion of the colors remained limited. From below or above (vertical) writing is well recognizable up to about 25 degrees due to the darkening. Colors invert obviously from about 15 degrees. A frontal seating position is therefore necessary for ideal images.ASUS G50VM-A1 Battery
The D in the name of our tested device stands for Dual. What is meant by this is the Intel Atom N550 (2 x 1.5 GHz, 45nm) processor,ASUS G50VM-A2 Batterywhich sits on the usual NM-10 Intel chipset. As with the N450/N455, the graphics core GMA 3150 is integrated. Since Hyper-Threading is still supported, the Dual-Core can process four threads simultaneously. This should expedite multi-tasking particularly, a scenario with which the Intel Atom could not previously get accustomed with its In-Order-Architecture. Whether this has changed is analyzed by us in the following paragraphs. ASUS G50VM-DP01 Battery
The N550 has a TDP of 8.5 Watts, this is three Watts more than a single core N450/N455. The CPU has a DDR3 memory controller, which is why a GByte DDR3-10600 RAM module (Kingston) is included.ASUS G50VM-X1 Battery
The graphics unit integrated into the processor (GMA 3150) offers a core clock speed of 200 MHz, and DirectX 9c support, which is not enough power for either games or decent hardware support. Further components include a 2.5 inch hard drive from Western Digital, with 250 GBytes of storage capacity (WD2500BEVT-08A23).ASUS G50VT Battery
How does the performance of a single core Atom compare to a dual core Atom? The N550 has a clock speed of only 2 x 1.5 GHz,ASUS G50VT-A1 Battery while the N455 is slightly faster with 1 x 1.66 GHz. We first tried the multi-core benchmark Cinebench R10 32-bit. The N550 reaches 1430 points. A N455 scores 840 (@1.66 GHz, Acer Aspire One 533-13Drr), or even 888 points (@1.7 GHz, Asus Eee PC 1016P). Abbreviated: Using all four threads (Hyper-Threading) the Dual-Core Atom processes 61 percent faster. The higher clock speed of a single core processor can't make up for this.ASUS G50VT-A2 Battery
How do things look when it comes to single core processing? The Cinebench R10 single 32-bit scores 509 points. A N455 also only achieves 568 (@1.66 GHz), and 581 points (@1.7 GHz) respectively. A disadvantage from the 1.5 GHz is therefore not apparent. ASUS G50VT-AK097K Battery
We wouldn't want to portray the Dual-Core Atom N550 as an unchallenged winner though.ASUS G50VT-B1 Battery AMDs Netbook CPU V-Series V105 (Eee PC 1015T) achieves 1021 points with only 1 x 1.2 GHz, although only in the single core test of the Cinebench R10 32-bit. Even faster is the Athlon K125 (1 x 1.7 GHz) in the 10 inch Acer Aspire One 521: 1491 points. Also concerning the system performance, measured with the PCMark Vantage, the AMD K125 can out perform the Dual-Core test device. ASUS G50VT-BBB Battery

Whether users are better off with a Dual-Core Netbook, can be revealed by the system benchmark PCMark Vantage.ASUS G50VT-X1 Battery Using this the One D255 can score 1498 points. Classical Netbooks with a single core N450 (e.g. Samsung N150 Eom) also score 1332 points. If the faster DDR3 RAM is used in conjunction with the N455, this also doesn't lead to significantly more points: 1160 points (Acer Aspire One 533-13Drr). If the N455 is overclocked to 1.7 GHz, then a score of 1230 points is possible (Asus Eee PC 1016P). Abbreviated: Our tested device is 18 percent faster than the best (overclocked) single core Atom.ASUS G50VT-X2 Battery
Taking another look at the AMD Netbooks, an AMD K125 (Aspire One 521) sprints ahead with 1686 points in the PCMark Vantage test (+ 12%). An AMD V105 (Eee PC 1015T) is however slower with 1360 points (- 9%).ASUS G50VT-X2AM Battery
Following on from the number crunching is the perceived working speed. This is noticeably smoother with the Aspire One D255, as well as with the AMD-K125 model (Aspire One 521), and hence more pleasant than with other single core Netbooks that we have tested.ASUS G50VT-X3 Battery
Does everything speak in favor of our tested device? In principle yes, ASUS G50VT-X4 Batteryonly perfect 1080p high resolution videos will still not be possible. The CPU load has fallen a little in Playback compared to the single core N455. Videos with a resolution of 1280 x 720 pixels (720p, H.264) can be played back without difficulties (approx. 65% CPU load). ASUS G50Vt-X5-RF Battery Full-HD test videos juddered sometimes though, and 82% CPU load on all four threads doesn't exactly speak in favor of the best video fun. It also depends on the coded format of the movie though, our 1080p trailers of a Coral Reef Adventure, and The Magic of Flight, posed no problems with a CPU load of 38%. ASUS G50VT-X5 Battery
Whether HD video is an important point in favor of buying or not is in the hands of the user. The rough WSVGA resolution is as much of a drawback as the missing HDMI port for connecting an external television.ASUS G50VT-X6 Battery
The Western Digital hard drive (type WD2500BEVT-08A23) with 250 GBytes works with a rotational speed of 5400 RPM. HD-Tune measured an average value of 51.5 MegaBytes per seconds (sequential read). This data rate is significantly lower than the average of comparable 2.5 inch hard drives in Netbooks, and also notebooks (approx. 65 MB/s). ASUS G50VT-X8 Battery
Those that wish to upgrade, will have it a bit more difficult than with other netbooks or notebooks. Firstly the keyboard has to be removed, then the screws for the base plate can be removed from the inside. Instructions with pictures is contained in the review for the Acer Aspire One 533. The SATA hard drive is very quiet. The noise could only be heard by placing the ear against it. ASUS G50VT-X9 Battery
The cooling fan on the Aspire One D255 is a constant companion. It does switch itself off when in an idle state from time to time (30.1 dB(A)), but when used only a little,ASUS G50VT-V1 Battery such as when starting tools or changing websites, it is still noticeably active (33.2 dB(A)). This is different to single core Netbooks, which can come to terms without a cooling fan in ideal cases (Dell Inspiron Mini 1012), or can switch it off for longer periods of time (Samsung N150).
