Apple iPad (March 2012, 64GB, AT&T 4G LTE, black)

Pros: The screen!
The 4G connectivity.
Dictation works very well.
Still a very zippy tablet.
Battery life is still excellent.
As always, the Apple ecosystem

Cons: Slightly heavier.
No Siri
Once you see the screen, you'll never want to go back.

Summary: I've wanted to do more with photos I take on the iPad and the combination of the new screen and the new iPhoto have answered my desires. The screen makes reading e-books that much better. The text is so crisp.

I wasn't craving 4G, but I must say that it is very fast! I live in a AT&T LTE city and I haven't roamed outside that yet, so I can't comment on 3G connectivity, but assume it is as good as previous.

The dictation works very well. Would have liked to have had Siri on this as well, but I have her on my phone.
