Nothing, actually! I was very good! However I had a good play with Leopard for the first time and had another look at the iPod touch and the iPhone. Verdicts:
Leopard: Spaces = brilliant! Time Machine = great! I need this.
iPod Touch: Good but is the addition of the internet enough to justify the money on top of a Nano?
iPhone: Hmm. Only £70 more than the Touch. But there’s the O2 tariff.
