Saw this posted in the Zune.net forums and thought you guys would like to hear (if it isn't common knowledge already) about the dynamic search. A lot of people have complained that you have type your search and hit enter to see results. However, if you just type when you're in the browse section it will begin to search. You'll see the text you're typing pop up in a transparent box. So yeah, just be in the browse (default) library view and start typing.
Oh yeah, definitely hoping to win the Zune 80

hee hee.
