I absolutely loved mine... but then I sold it. My regret was not holding out for the 3G unit, so that is what I am doing now, patiently waiting, (while the friend I sold it to mockingly displays it on their desk every time I walk by, lol.)
I am also getting a 32GB whereas the WiFi unit I had was 16GB. I feel that having more storage is a way of future-proofing the iPad a little... unless you plan on selling it next year when the second generation model is released, I would go with 32 or 64 gigs for sure, (if you have the budget.)
Other than that, you will love it. It really is a great device and it will only get better in time when developers really let loose and create new, amazing apps... not to mention this Fall when it gets some of the new OS 4 features like multitasking.
