The iPad 3rd gen is a big improvement, but many of the features will take time to fully appreciate. The screen resolution is a major issue with the naysayers, yet it is new and many things that take advantage of the high resolution are not changed to take advantage of it. I only really notice it in some of the high rez photos I have, and some of the print. Look at it this way. On my 1080p HDTV right now, the new shows are beautiful looking. An old show from the 80s, on another channel, looks like mush in comparison.
I am extremely impressed with 4G. My home HS DSL will top out at 5 Mbps, which is better than it was a month ago. My iPad with 4G tested at 21 Mbps at the same time. Now if the servers and land lines would get improved, I would be in hog heaven.
The camera was something that I did not expect to use much, but after using it, I may get a lot of use from it. It may take some getting use to, but the picture quality is great, and it is extremely fast. It may take awhile, but it has more potential than I expected.
There are other features exclusive to this iPad that will take some time to fully appreciate, but just like with my original ipad, it will be a journey worth taking.
