Since images have already been posted, i'll skip that. Impressions:
1) The thing is very light, supposedly a bit heavier than the regular mini but I don't see much an difference from extended use. Still that beautiful, thin and light design that works so well in one hand and is a pleasure to thumb type on.
2) The screen...THE SCREEN. Stunning, absolutely stunning. It's got the same PPI as my iPhone but on that 7.9" screen it's absolutely astounding. Holding the device at half or full arms length, the difference between it and the regular iPad retina screen isn't noticeable. But when you've got them up closer to your face you can definitely notice the extra sharpness with the mini.
3) Best fucking iPad ever. Love it to bits.
