In my recent emergency trip this past week (brief update: My Dad is not out of the woods but the path ahead is a clear one), my iPhone 4 became my most used and primary computer for many reasons. This despite the fact I had both my iPad and MacBook Air with me and close at hand. It was the one best fitted to almost every situation I found myself in. Unobtrusive, agile, and the one with a constant and reliable internet connection.
Look at the list of things he did on his iPhone while away. That’s why these devices are such a big deal: they allow you to do things you could never have done before. They’re way beyond what a PC can do, and it’s why it’s irrelevant to sit here and judge them by a PC checklist of features. They’re different devices entirely, have different uses, and create all kinds of new possibilities. It doesn’t really matter if they’re a PC or not.
