you forgot to mention the Zune has way more bugs and does crash. Every store that I went to buy it from had a defective display Zune that wouldnt work and everyone is returning them. And theres really no need to have the share songs or share songs to your xbox when you could easily just download them.
My Zune hasn't 'crashed' once. Lol. Maybe the customers are stupid and don't know how to handle a portable device? And yes, playing songs on your xbox360 is DEFINATLY a good convience, trust me. A few new software upgrades the Zune needs: A readily visable clock. A stopwatch (for my runs, the iPod 5G's have em.) Maybe a few games, don't need them though. Can't wait for rockbox to have a nice release that makes the Zune even better. Imagine them being able to have special network drivers that enable internet use via "Zune Linux". Wow.
I have an iPod video 80gb which is nice, I like the zune too. Only thing about the zune that I like is the screen size.
