My own mobile phone contract expires next May, and as Vodafone, my supplier, are due to start selling the iPhone in the New Year, I will confess to having been tempted to upgrade to one.
Many of my colleagues are surprised that I haven't gone for an iPhone before. However, although I use Macs a lot of the time, I'm not a slave to the product. For me, the iPhone has always been to expensive, especially given the fact other phones can do better in key areas. That said, the iPhone seems to have matured into a decent product and costs have fallen. Although I've been a Win Mob fan for the last two years, the time for a switch may be coming.
If it does, I just hope I don't develop any un-natural emotions as a consequence.
