Today's the day, folks. The Zune HD has been released. A new interface, strong hardware and high expectations. Oh, and the strong assumption that we'll see a strong Zune UI influence in Windows Mobile 7. (We're already seeing some in WinMo 6.5, namely in the home-screen interface.)

For our part, we'll take a look at the Zune HD and see what's what. Anything you want to see in particular? Let us know in the comments.

Oh, and I'll be joining the boys and girls on iPhone Live at 8 p.m. EDT Wednesday, where we'll give the Zune HD and iPod Touch the what-for. Be sure to get a seat the chat room early; we're expecting sparks to fly.
