ViewSonic ViewPad 7 tablet going for Sale on Amazon

ViewSonic ViewPad 7 tablet is now available for sale at Amazon,where it retails for $600 a pop as a pre-order, although the listing does mention "Temporarily Out of Stock".

It has front- and rear-facing cameras. It is powered by a 600MHz ARM processor, carries 512MB of internal memory, a microSDHC memory card slot, Wi-Fi and Bluetooth connectivity, an integrated GPS sensor and a rather low resolution of 800 x 480 pixels. 

One thing that makes the ViewPad 7 stand out would be its ability to handle voice calls.
