The Camangi WebStation has been floating around for a few months now in little more than proof-of-concept form. Now, it's on the cusp of being a real product, releasing in the US next month for $US400.
The system runs Android 1.5 through its 7-inch (18cm) 800×480 glass touchscreen display, plus you get Wi-Fi (b/g), GPS, microSD reader, 2-megapixel camera, 0.3-megapixel webcam and a USB port that can always add 3G (though, the whole idea becomes sort of silly at that point).
Plus, a built-in stand on the back means it can double as a picture frame. Yes!!
