ViewSonic said today that its new Windows and Android tablet, first announced in May, is now on-sale in North America in limited quantities and should be widely available later this month.

The ViewPad 10pro is billed as dual OS system but it really is a Windows OS device which can run Android 2.3 as a virtual machine on top of the Windows 7 Operating system.

That means if Windows crashes, so does your Android 2.3 virtual machine.

Powered by a 1.5GHz Intel Atom processor Z670, the new tablet features a 10.1" screen 1024x600 capacitive multi-touch panel, 2GB of memory, 16 or 32GB SSD, Wi-Fi and Bluetooth connectivity, a 1.3 megapixel built-in front camera, microSD slot and an HDMI out port.

Viewsonic says the device is designed for business users who work in the Windows Operating but also want ability to switch to entertainment and personal apps in Android.

The ViewPad 10pro is available in two configurations: Windows 7 Professional version with a 32GB Solid state hard drive (SSD) for $700; and a Windows 7 Home Premium version with a 16GB SSD hard drive for $600. Both versions come with the Android 2.3 app.

A docking station accessory will also be available for $60.
