I have a brown Zune too. When I first got it, I absolutely loved it. 30 GB of storage, ability to play photos, videos and music either in headphones or on my TV. Then a strange thing happened... Last September I wanted to get a mobile device that allowed me to surf the web. I saw my friends' iPhones and thought it was a good experience. "No problem" I thought. I'll just check out this Windows Mobile 6 stuff. I started on a hunt to find a non-iPhone that browsed the web as well as an iPhone. I went to AT&T stores (since I had their service already though my contract had expired), Verizon stores and Sprint stores. At the time, every other phone's web surfing was a J-O-K-E compared to the iPhone. A joke. I can't tell you how much it pains me to say that, since I am in reality a Microsoft fan and have used their development products professionally for over a decade and a half.
So I got the iPhone 3G. My Zune was then in the glove compartment of my car for a few months. I pulled it out a few weeks ago to try out the Zune games that seemed to be taking off. What I used to think was a sleek, intuitive interface on the Zune now looked clunky. The entire device actually felt cheap. The Zune hadn't changed though - I did. I got used to the iPhone. But anyway, I upgraded my Zune firmware, installed the Zune Games and actually tried the default ones out. Texas Hold'em was actually fun. But man, the experience is nothing - NOTHING - like the iPhone.
I guess I'll try selling my brown Zune on eBay before they become totally worthless.
