I got an iPad the first day the wifi model came out. I've really enjoyed it - it's the first Apple product I've bought since 1979 when I bought an Apple ][+. I'm happy with the iPad in most respects, but I'm not happy at all about the way the Apple has limited access to the device. I'd like to be able to write software for it just like any other computer without having to go thru Apple's store or being forced to use Apple development tools.
Other than that, it's a great device and I pretty much take it with me everywhere I go.
