Ok, I've been playing with it again all night & 2nd time around it droppped in perfectly, no problems at all. Not too much more to add save to say I've been messing with the media centre & took a few shots for those who like this sort of thing - Gonzo? Turin??
The image behind the album cover is all your other album covers & it scrolls downwards as the record plays. That is cool!
This is new too. Keeping the left/right buttons held down whizzes through the music library & every few seconds a cover pops up to tell you where you are. Handy for a big library.
The main menu interface has been made over & additional options added. A definite improvement.
All in all, I like it so far. Beta for sure & tricky in places, but if it keeps on like this, then it'll lay vista to rest as it ought.
