I got a Zune for Christmas, from my employer. Here are a few reasons I hate it.
#5 - It's really cool looking, and people keep wanting to touch it.
#4 - It holds WAY more music than I can possibly listen to. I've downloaded everything in sight and it's still not full.
#3 - My Zune Pass gives me way too many choices. There's so much stuff on there I just can't download it all fast enough.
#2 - The video screen is so big, when I'm travelling, other people keep looking at it to see what I'm watching.
and the #1 reason I hate my Zune...
The sound is so good it drowns out everything around me. I miss phone calls, conversations, etc...
