At some point I’ll post some detailed thoughts and opinions of the iPhone, now that I have one, but here’s a few to be getting along with:

1. The iPhone demonstrates so dramatically what’s wrong with user interaction on desktop and laptop computers, and that extends to applications, websites etc.. For the majority of its use, the mouse – a device pioneered by Xerox and then Apple – seems antiquated now that we have touch screens.
2. I wrote before about the dawn of ubiquitous computing. The iPhone really does mark this event, but it does so in ways that I never imagined. What could be more personal than the Personal Computer? Even PDAs and the Apple Newton still feel like computers when compared to the iPhone. I’m not in a position to describe how it makes me feel, or indeed what my relationship will be – but it could be that the iPhone is the first truly personal digital assistant (if I may use such a vulgar term).
3. YouTube is the killer application, because it’s more personable, quicker and easier to use than its web equivalent.
