I know quite a few who in the last year have made the switch from Dell to apple - under the encouragement of one of those 'apple is better' believers. Most are very happy with the swicth (they sound like Grumble there), though some have had particular problems too. One has a constant problem with the Mac dropping the wireless signal and then having great difficulty reacquiring it, while the Dell sitting next to it has had no trouble at all.
Right now I'm getting to do a nice comparison because I spend half my time on a PC and the other half on a Mac and I still haven't come to a consensus.
I do enjoy the iPhone though EXCEPT for the call quality. Lucky for me I do more texting and checking e-mail than anything else!
