Expert Review


Want a 3D-graphics boost, but don't want to sacrifice much battery life, portability, or money? This could be the right laptop for you.

Very beautiful machine. Superbly slim profile and good quality build

Too slow. Performs like a netbook but has the appearance of an ultra-portable laptop
