We promised to dig up ViewSonic's dual-booting Windows 7 and Android 2.2 ViewPad 10Pro tablet when we got to Barcelona, and here we are delivering on our word. We just got a chance to check out the 10.1-inch slate and we have to say hardware-wise, we're dealing with typical ViewSonic quality -- the 1024 x 600-resolution, capacitive screen isn't exactly high quality (horizontal viewing angles were pretty bad) and the build was mediocre at best. However, software-wise we have to say the 10Pro is pretty interesting -- the Intel Atom Oak Trail-powered slab boots Windows 7 Home Premium, but is running Android 2.2 on top. Unlike the first ViewPad 10, you don't have to reboot the device to switch between Android and Windows as the Google OS is running as a virtualization. No word on the pricing of this one, but it should be hitting the market this May. Hit the break for a quick look at the relatively-quick Android / Windows hand-off.
