Viewsonic has unveiled the first ever dual-boot Google Android and Windows-based tablet PC. The Viewsonic ViewPad 100 is a Windows 7 Home Premium touchscreen tablet PC that can be optionally booted in to Google Android 1.6.

Viewsonic says the ViewPad 100 tablet PC offers "the speed and portability of an Android-based OS without sacrificing the power and compatibility of a Windows powered system". 

The £549 tablet PC comes with a 16GB solid state disk drive and has 1GB of DDR RAM. The 10in screen has a resolution of 1024x600 pixels and has a capacitive multi-touch overlay. The device has a built-in 1.3Mp webcam and a microSD card that accepts cards up to 32GB capacity. The ViewPad 100 offers Wi-Fi and Bluetooth connectivity, assisted GPS navigation and has a G-Sensor. It comes with USB 2.0 ports and supports video output through a mini VGA port.

Set to go onsale in October, the Viewsonic ViewPad 100 is designed for mobile web and email access. It comes with the Google Chrome web browser and is able to display Flash media content. Powered by a 1.6GHz Intel Atom processor – the same chip found in most netbook computers – the Viewsonic tablet is intended to offer superior speed to a netbook and be more portable than a laptop.
