My Nokia N900 has an 800x480, 3.6" screen, and a PPI of 266(google'd for that number). That means I have a screen that's ~3"x1.8".
This means that a 1024x600 screen should be ~3.85"x2.26", or ~4.5".
A device like that - if the bezel was small enough - a tablet like this could fit in my pocket! Yet, they are using a screen that's a bit over two times the minimum size for that resolution.

Yea... I'm not entirely impressed.
