Conclusion: It may be priced competitively, but the ViewSonic ViewPad 10 it doesn't come close to competing with the best tablets available. Windows is crippled, Android is out of date, and the elegance promised by tablets is replaced with lumbering awkwardness.
Pros: Dual-boot offers Android and Windows. Windows OS supports Flash.
Cons: Tablets aren't Windows friendly; you'll miss your keyboard and mouse. Android 2.2 isn't the tablet-specific Honeycomb, just scaled up smartphone software. No Android Marketplace. Button functions change depending on what application you're using. Tweaked Android OS doesn't support Flash.
Summary: The $679 ViewPad 10 feels like ViewSonic took a Windows 7 tablet and decided to throw Android on at the last minute to give it greater consumer appeal. While the Windows 7 experience is passable, the Android implementation is pretty awful. You can't turn the screen off without turning off the device itself in Android mode, the app selection is poor, and you don't get enough battery life.
Pros: Attractive design, Decent Windows 7 performance
Cons: Screen doesn't turn off in Android mode, No dedicated volume controls, Confusing button layout, Windows 7 slow to rotate, Short battery life, Small Android app store
