Just to echo what others have said-
I've had about 4-5 phones since 1999 and most of them were needless.
Also: unibody Macbook etc
You make me feel bad. I got my first mobile at the end of 2003 and I'm on my 4th . . . I could have cut it down to 3 if I'd just bought an iPhone when they came out.
I'm currently in a foreign country which is somehow giving me the illusion that money doesn't matter. This means I keep wanting to buy a MBP when my iBook still works great
