Now that my upgrade is done, here is a list of issues that I have experienced on my iPad 4 - 1. Lag while changing the orientation with the onscreen keyboard activated. This is pretty bad actually. 2. The lock/unlock mechanism is mostly hit or miss. 3. Gesture-based actions are not smooth. Can someone please check issue#1 and post back? This seems to be pretty bad. I can live with the other issues though. All in all, my iPad is no longer as smooth as it was in ios 6.1.3, from which I had upgraded, skipping the 7.0 update altogether.
