Lets be clear, it is the development version - advanced prototype. Teh plaszma system is not really near completion and video seems unstable and music is hard to navigate. But sound is great and video looks good - it blows the touch and hopefully will make it look like a donkey.
However, I have installed android this morning and the sd card integrates flawlessly. Yet, I can't add stuff to the main memory (or have not found it yet).
I'd really have liked a zune hd except living in the Uk makes them hard to get.
