Viewsonic, a company that has been producing displays for more than 20 years, has announced that it, too, will be taking part in the Android tablet market.

The Viewpad 7 (see our hands-on), which will run Android 2.2, features 512MB of onboard memory and up to 32GB expansion via a MicroSD card and will be accompanied by the Viewpad 10.

One very interesting fact about the Viewpad 10 is that it will run Android 1.6 (boo), but also feature the option to dual boot it with Windows 7 (yay), and will be powered by a 1.6GHz processor and contain 1GB of on board memory. The 7-inch version is expected to launch by the end of the year for $479, while the 10-inch version is expected in Q1 of 2011 for $629.  [Viewsonic]
