I bought the iPad 64Gig 3G when it launched. I took it to New Zealand the next day. In fact, I might have been the first person in New Zealand with a 3G ipad. From the time it launched in the US, only about 1,000 people could have beat me there (three flights before mine).
Anyway, I love it. I use it every day. My wife took her laptop with us, and I left my laptop at home.
Netflix streamed on it from 3G looks great. So does Hulu, but not about to pay 10 bucks a month for it. I also use EyeTV, so from anyone I have an internet connection, I can watch live TV from my house, or anything I have recorded.
It's a great device. Oh, and I never put it in a case. I just skinned it so it won't scratch (and it's less slippery) and use it as is. Makes it very easy to use with one hand.
Only thing that sucks about it, is I also have an iPhone 4. With the screen on that, and iOS 4.0, the iPad already feels a little outdated. Putting iOS4.0 in it when it comes out with help.
