Pros: Low price per Gig. Nice UI. String drivers.
Cons: Me and the touch screen don't always agree on what I'm trying to do.
The UI is very easy to navigate and the screen looks great. I only have two complaints, the touch screen sometimes has trouble telling when I am swiping and scrolling, and the screen sometimes pulses when navigating the UI.
My IEMs sound great. The Zune also manages to drive my Denon D5000 satisfactorily though an amp is definitely needed for any high quality cans.
The apps market is pretty weak though with a total of 30 apps or so. However, Facebook and Twitter apps are available which should be enough for most people.
Why I bought it.
Zune HD: ~200$
