The older 10-inch CE/Android netbooks definitely had a different battery, but it's hard to say whether the battery life is the same because there's great variance in battery life between different 7-inch models. Yes, Chuck E, there is a Windows CE 7, but it's officially called Windows Embedded Compact 7. As for the differences between that OS version and CE 6, it depends in large part on what the OEM chooses to include. The Sylvania SYNET7WIC doesn't include Internet Explorer Embedded, for example, Sylvania opting for the much older IE CE 6.0
(yet the SmartQ V5, with CE 6, had IE Embedded
). I'd expect the faster CPU to provide a bigger advantage than the newer OS. There are several of these on eBay right now.
