Acer Aspire TimelineX 4820TG-6847

How much power can a 4.6-pound notebook really offer? More than you might think. Thanks to a second-generation Intel Core i5 CPU and AMD Radeon HD graphics, the Acer Aspire TimelineX AS4820TG-6847 ($729) outperforms most of the competition and looks good doing it. Perks such as Dolby Surround Sound really sweeten the deal, too. Read on to find out how this thin-and-light speedster compares to the competition.Understated but elegant. That's how we'd describe the chassis of the TimelineX AS4820TG. The lid has a black brushed aluminum finish, while the palm rest has a lighter brushed metal treatment. Glossy black plastic surrounds the display and keyboard, which adds a nice accent but picks up fingerprints.Above the keyboard on the left side of the deck is a grooved circular power button, next to which are LED activity lights. Two speakers separated by a Dolby Home Theater Virtual Surround Sound label sit in the center, and two thin black buttons--one to launch the Power Smart Manager and an eject button for the tray-loading DVD drive--are on the right side of the deck.After playing a Hulu video at full screen for 15 minutes, the TimelineX AS4820TG stayed well below the threshold of what we consider uncomfortable.
