I was a faithful Zune customer for years until I had just had enough.. too many times had I had problems or malfunctions. I decided that the Zune just wasn't hardy enough for me. I mourned for a minute over the sweet custom art that Apple doesn't provide and then switched over and got an ipod touch. I've had no problems with it, and it was pretty reasonably priced.
So.. unfortunately after giving Microsoft a long try, I'm now an Apple customer. I'll never get a MacBook though!
