The Acer Aspire One ran for 2 hours and 14 minutes on our video playback battery drain test, using the included 3-cell battery. That's barely more than the MSI Wind, which was also saddled with a puny 3-cell battery--and the biggest flaw for both systems. MSI plans to upgrade its battery to a 6-cell version in the near future, and Acer offers a 6-cell battery that we've seen online for $119--a large premium for such an inexpensive laptop.
The Aspire One includes an industry-standard one-year parts-and-labor warranty, and Acer has set up a separate mini-site for the Aspire One, including a page labeled "drivers and support." Unfortunately, that support page, and its subpages, have no content aside from a note that says, "Updates coming soon." The regular Acer Web site has some FAQs and driver downloads, but the tech support number is impossible to find (it's 800-816-2237), and the phone support hours are only 5 a.m. to 7 p.m. PT weekdays, and 6 a.m. to 3 p.m. Saturdays.
