WOW. I was prepared based on what I had heard from others that the screen would be amazing, but it didn't prepare me for how good this thing is. Better color, better brightness, and amazingly clear graphics. The only bad thing I can say about this screen is that web photos really need to improve, because they look like crap a lot of the time on this screen.
The speed is the other thing that suprised me. Having been in the tech business for a lot of years, I know that increased video processing can make a huge difference in games, but I wasn't prepared for how much it would improve every part of the experience. Even opening and playing video from the web was amazingly improved. Whether this is all due to the improved processor, or is also impacted by the increased RAM, it is really a sight to behold.
I haven't tried any really intense games yet, because most of the last two days has been using the things I always use everyday to see how they are improved. I also have been repourposing my iPad 2 64GB 3G for the wife to replace her iPad 1. Since she uses her iPad for work, getting it dialed in and making sure everything is working the way she wants it to in preperation for work on Monday has been a priority.
I will spend time this week really putting the NEW iPad through it's paces and reporting back here.
