I could be wrong about the Zune's prospects. If it takes off, though, it would be so undeserved.

The reason I am sceptical about the wifi sharing is not just because Microsoft is implementing it very badly. Look at how commonplace laptops have become (in other words how easy it is for a laptop user to run into another laptop user) and yet no one is trying to promote laptop-to-laptop connecting, not Microsoft or anyone else.

And even the Nokia 770 equipped with the Ultimate Sharing/Streaming Application would still face two obstacles in this area: 1) little storage space and 2) too few 770s out there.
