I've got a PowerBook that's been relegated to desktop use after a bad drop on it's DC (power adapter connection). When I got my iPhone it was great to do some casual web browsing around the house. It seems I'm staring to use my iPhone more than my Mac to check email/schedule, read RSS, track packages, check sports scores/TV listings, and of course play games. There are days when the only time I'll use my Mac is to sync my iPhone. Has your iPhone changed your daily use of your computer?
