At the core of the Acer Aspire S3 951 (2464G34iss) provides apower-saving Intel Core i5 for a clock frequency of 1.6 gigahertzspeed. With four gigabytes of RAM, the Ultra Book work tasks in Wordand Excel performs with very high speed - the more expensive MacBookAir but was a tad faster. The same goes for video editing, such asthe reduction of a filmon a Tablet PC. For complex games like"Battlefield 3" good for the S3 just as the MacBook Air,the graphics processor is suitable for simple but titles like "TheSims 3".

The matte gray casing is made oflightweight aluminum-magnesium alloy. The 13.3 inches (33.8centimeters) wide screen (1366x768 pixels) is a bit dark and glossysurface adds extra reflections. Mouse buttons do not exist, this isthe whole touchpad clickable. The processing of the S3 remains behindthat of Airs: The touchpad does not fit exactly into the case, themonitor has a slight blue tinge and is very wobbly - annoying ontrain journeys. The arrow keys are puny.
