I literally have people running up to me at church and saying, "Guess what I just got for Christmas! An iPad!"
And I understand their excitement. I don't own one (yet) but I played with one for five days before delivering it to my grandmother – which has been a great success, by the way. I've seen children and IT guys, grandparents and teenagers just sit down and start using it. People want to stand over your shoulder and just watch you. Because it works. And it's beautiful. And people go "Ooh" and "Ahh" and smile a lot.
And this is the first generation of the device! I can't wait to see it evolve over the next couple of years. I really think the iPhone 4 is a huge step up from previous iterations. How much more amazing will be the iPad 2 or 3?
Anyway, in celebration of how Apple got it so right, here's a great little article from Wired on why you don't want to buy a Windows Slate tablet computer.
