A quick shout out for iOS 4.3. I’ve upgraded my iPad now (my Verizon iPhone doesn’t yet have 4.3 available. One of the best features for me will be the speed improvement in the browser.

Personal hotspot doesn’t excite me, but I’m sure it will be very useful to some folks. For a good summary, see this link from Network World.
