Asus Eee PC T91 review: Asus Eee PC T91

Our main knock against the Eee PC T91 is the inclusion of the 1.33GHz version of Intel's Atom processor, instead of the more common 1.6GHz N270 version (or even the faster 1.66GHz N280 that Asus is particularly fond of). The 11.6-inch Acer Aspire One 751h made the same mistake, and in our benchmark tests, both the T91 and the Acer Aspire One 751h fell behind other Netbooks.

While the performance difference was not enough to be a deal breaker, Netbooks are generally pokey products to begin with, and even a tiny bit of additional slowdown can be frustrating. We'd trade a little battery life for a powerful processor and a zippier overall experience (although even with the slower CPU, the custom touch apps ran smoothly most of the time).

The Eee PC T91 ran for 4 hours and 20 minutes on our video playback battery drain test. That's impressive (even if Asus' 10-inch 1005HA Netbook ran for more than an extra 2 hours on the same test), considering the small chassis requires a small battery, and the additional drain of powering a touch-screen display.

Asus covers its laptops with a standard, one-year, parts-and-labor warranty, and it offers online Web-based help and a toll-free phone number. The company's support Web site is easier to navigate than it used to be, and includes easy-to-find driver downloads FAQs.
