"Better but with some disappointing shortcuts"2.5 starson by dkunzman1
Pros: Thinner and lighter making it feel better in the hand.
Dual core makes apps to run smoother / faster.
Cons: Glass is thinner - worried issues will arise
Only 512mb of ram - could have easily and should have gone to 1gb
Camera is so-so.... expected same quality as i4.
No improvement in sound or wifi signal
Summary: I looked, I played but decided against replacing my existing iPad (16gb wifi version)
At this time I see no real reason to upgrade.
Will focus my sight on an Android or other tablet instead.
Though it will likely sell well (based on the lines I saw) I feel Apple really let it slide by not providing any innovative or significant improvements.
Sorry Apple, I think you missed a great opportunity.
