I want one. My daughter wants one and my wife isn't saying (but she wants one).
My hesitancy to getting one is that it's 1st generation. For how expensive it is I don't like the idea of being part of the first release. If they would announce that future developments (such as adding a camera feature) will be able to be retrofitted I'd be more likely to just get one.
Another thing is that I anticipate it being as much fun as my iPod Touch but with the Touch I can carry it in my pocket. Probably the best thing about the Touch is that it's so accessible. As an example, the Kindle is about the same size as the iPad but when not at home I read my Kindle books from the Touch. Even while waiting for an elevator I just take the Touch out of my pocket and read a page or two. I wouldn't be able to do that with the iPad. Too big.
Too late to get on the bandwagon there will surely be a whole accessory product line to the iPad that will produce small sling pouches or bags for the things. I can see carrying something like that because I don't lose things, but my wife? I suppose iPad theft/loss insurance will be available (and worth it) too.
