It was first mentioned a couple of weeks back, now ViewSonic has given the ViewPad 100 tablet an official launch at the IFA trade show.Why the big news? Well, it's the world’s first dual-boot tablet, packing a 10-inch screen to view full versions of Windows 7 Home Premium and Google Android 1.6. Yes, 1.6 - we would have hoped for 2.2 as well.But on the plus side, you can quickly check your emails or browse the net with Android, whilst still being able to access all those PC essentials if you are working on the go, like the ability to create presentations and Word documents from scratch. Operating systems aside, the ViewPad 100 also offers up a built-in 16GB SSD, an energy-efficient Intel Atom N455 1.66Ghz processor with 1GB DDR3 RAM, which should mean a hefty battery life plus a capacitive multi-touch display, built-in Wi-Fi and Bluetooth connections, a G-sensor, a Micro SD slot for up to 32GB of storage, Assisted GPS for navigation, two USB 2.0 connections and a built in 1.3-megapixel webcam. All of that will be available from October 2010, priced around the £549 mark.
