I am defintely not a rapid Apple fanboy (I do windows work mostly) but I can say I agree 100%! I've been using the iPad for work since it came out last year (email, meeting notes, Logmein/Gotomypc, Programming reference books, etc.) and I can say in the 1.5 hours I been working with it so far, the new one is much much faster in every aspect I have tried.
I was annoyed the resolution did not change but it looks like the boost in speed and memory will make up for it.
Another note for those who asked, it is not any lighter weight-wise but the thinness does seem to make it a bit easier to carry. Of course, I'd never use it with some kind of wrap-around case (Dodocase for me).
Thanks,
Larry
