That's what the wife keeps calling me after my latest purchase. I have no reason or excuse other than I "wanted one". I never bought an iPod, but I did buy the iPhone. Trust me, it's an upgrade to the craptop.
Still playing with it, but already hooked. Setup was a little murky in that I had to go to an AT&T store to get a confirmation code, but I think that the credit check used your existing payments from iTunes, for which I had none, so nothing to check against. Once I had the code, it was all good.
I suppose the truly geeky thing would be to say that this post came from the iPhone, but I'm not that bad . . . yet! *laughs*
