"The S12 is a very sleek and powerful netbook. It combines looks, portability, and function into a very affordable package.
Processor: Unlike its sister models which feature the Intel ATOM processor, the VIA Nano model adjusts its clock speed according to what power scheme the computer is set to. The processor reaches 1.6Ghz at the two highest schemes. This feature in tandem with the higher Front Side Bus speed and larger L2 Cache make this model the obvious choice when it comes to processing power. Multitasking is possible, but does have a slight effect on performance (nothing unbearable)
Memory: Another advantage of the VIA Chipset is that it is compatible with PC2-6400 RAM, that is RAM with a speed of 800mhz, much faster than the 667mhz available in the Intel Chipset. I have put a 2Gb DIMM in my S12 and can attest to its ease of installation.
Storage: For a netbook, the S12's 160GB hard drive is average, but the factory set partition for one key restore is very handy. It does limit the internal storage to 100GB, but for a netbook that is plenty. The hard drive is also easily upgradable to a larger capacity drive or SSD.
Graphics: The VIA Chrome9 graphics are like any other integrated graphics; not the greatest. However, they do get the job done. Videos were slightly choppy, but many other factors influence video playback.
Battery: The one downside to the VIA Nano chipset is that it does use more battery than the Intel models. I have gotten 3 to 4 hours of use out of the battery before it is completely dead. During these times the computer had the wireless card on and internet running, so more life could be achieved if plugged in via ethernet.
Display: Excellent LCD with crisp resolution capable of 720p video. Glossy display looks nice and is not too reflective. Brightness is adjustable and can be set very high.
Pros: Small size, excellent selection of ports (SD, USB, Express card, VGA), high performance in its category, good wireless reception, easily upgraded memory and storage, build quality, and full sized keyboard.
Cons: Battery can be short lived, no bluetooth (hopefully this is easily installed like on the S10), graphics can be disappointing, and some of the pre-loaded software can slow the computer."
Cons: Included Software, Build Quality, reliability
"Great keyboard, great screen. Big improvement over 1024x600. Nano processor runs Mathematica benchmarks almost twice as fast as 1.6GHz Atom (score 0.59 vs. 0.31).
USB devices spontaneously disconnect, reconnect. System often freezes for a few seconds—more than XP usually does. Out of the box, HD had heavy fragmentation--included defragmenter is sloooow. Wireless connection is finicky--sometimes the automatic connection has to be retried manually several times. HDD is partitioned, so you can use only 103 Gb. QuickStart is nearly worthless to me because it usually won't connect to wireless. [Strong signal, WPA-2]
On the whole the Ideapad seems to be of significantly lower quality than the MSI Wind. It's still a nice computer, though--I hope mine lasts."
