You didn't mention the 128MB of faster GPU RAM in addition to the 512MB of slower system RAM.
No mention of the accelerometer and gyro (for six degrees motion detection).
The GPS that is featured only in the 3G model. The standard WiFi only model will use Skyhook in place of GPS.
Also, on the camera front both cameras are 0.3 MP and run at 60 frames per second in 640x480 resolution and at 120 frames per second in 320x240. The reason for the low res but fast framerate is because the cameras are built for gameplay / interactive purposes rather than as a replacement for your main photo / video device.
Nevermind, didn't realise the window to re-edit had long passed.
