They were out of stock on the $400 model, and I had to act while my resistance was low. So my wife and I walked out of the store $500 poorer but feeling oh-so twenty-first century.
People, myself included, seem to be buying these machines based mainly on their potential. A certain number of applications come with it, such as the Safari browser, email, a notepad, a calendar; other apps are free or modestly priced. Nota bene: so far, all of this duplicates functionality already on my laptop. I purchased a Sudoku game and use it a lot, but could have kept playing on my laptop for free. There is a free app that lets me read all my Kindle purchases in an appealing display, but I already own a Kindle. I can upload photos and music, but I already use my laptop for that. There's an iBook app I don't use yet because my Kindle books won't transfer over. Other apps exist, but they are still relatively few.
So I ask myself, potential for what? Simply for the uses I haven't thought of, the surprises developers will dream up.
Meanwhile, it's hard to see the iPad fulfilling any immediate need that my other gizmos can't satisfy quite well. I love it, but so far it's mostly an expensive Sudoku-playing machine.
