Only apple product I have is an iPhone, and I love it. Had E71 before and got sick of worrying about signing all of the apps I wanted to buy, terrible music player, slow internet and having to back up and reinstall every single app every time there was a firmware update.
Fact is, iPhone is the most capable mobile device right now. I easily manage all of the servers at work from this thing, I play great looking games, I write music on it and I never ever had to reinstall anything, set anything up, fiddle with settings, or spend more than 10 minutes updating the phone. I have a family and I prefer to spend my time with my son, not my phone/computer.
As of their computers, once again, I see the appeal. They are easy and time saving for people who go online and upload/edit their photos/videos on their computers, which is pretty much all I do on my laptop now. So, I'm pretty sure, my next computer will be an iMac, just because I don't have time for a PC.
EDIT: Jees, few too many "computers" in that last paragraph.
