No bigger than a portable DVD player, the sleek, ultraportable ASUS S6F ($2,200 street) has a built-in optical drive and a DVD-friendly widescreen that allow it to function just like one. But unlike those dedicated DVD devices, the S6F can compute as well, thanks to its full-blown edition of Microsoft Windows XP Professional. It's an ultraportable fit for the skies, not to mention road trips, family vacations, and even your daily commute. Just be warned: The cramped keyboard is only great if you have tiny fingers.
