I'll probably buy one in a couple of years, once they get to the third revision. Definitely needs a camera in the front for video conferencing. I like form factor, smaller than a laptop; I dont like netbooks, a bit too small for me. I can see myself ditching the laptop for one of these ipads.
Id really like to see how the oreilly safari books work on these devices, whether they're readable. I could definitely see myself plumping for a safari subscription, heck would be worth it what I spend on tech books every year.
In the end, still too expensive, when they get a model down to $300, thats the sweet spot for me.
