Zune Phone Feature Wish List

"Now that we all know about the supposed Zune phone rumors, several websites have decided to list their opinions on what would make the Zune phone successful... Ok.. all nice and dandy.. but somehow this all feels very constrained to me. I don’t believe we’re thinking outside the box enough. So with that said, here are my suggestions to what would make an awesome Zune phone..."

ZuneSphere sums up a few of the wish lists floating around for the rumored Zune Phone, and offers up an expanded list of features and functionality. Some of these features, such as enhanced Wi-Fi, replaceable battery, and streaming functionality, would be nice for any Zune model, not just a phone edition. Personally, I'm not sure I'd be too interested in a Zune Phone device. That being said, I do hope that the Zune team is looking at making more than just a mobile phone that happens to play music. A Zune Phone needs to take advantage of 24/7 connectivity. Namely, it must be able to directly interface with Marketplace, and it should allow for long distance sharing, not just short-range Wi-Fi sharing. What features do you feel are critical for a Zune Phone?
