I've owned an iPhone for nearly a year now. I used to keep a watchful eye on the cell phone market; always looking for something better than what I had to come out. If nothing else, I've changed my outlook on cell phones...until I have a pressing need that the iPhone cannot deliver, I'm sticking with it.
I've owned a handful of iPods...still have a few (shuffle, nano, video). I have also owned a Zune. There are pros and cons to each. For me, the 30GB iPod Video suits my needs just fine...even though I recently cracked the screen (not to the point I can't use it, but it is noticeable). I sold the Zune to a friend, but not because I didn't like it. Rather, I sold it because I DID like it, and knew he would enjoy it more than what he was going to buy instead (couldn't afford a new iPod or Zune).
I've owned a few Apple computers, including an iMac and a Powerbook. However, I am a Senior Systems Administrator for a upper-medium-sized business, and it simply makes more sense for me to use PCs for the majority of my duties...I need to test from my users' perspectives, and there's simply more PCs connecting to my equipment.
