Ok, well I received this bitch earlier today. So far I like it quite a bit and haven't had any actual problems with the player itself. I personally find the UI, features, and transfer methods far better then that of an ipod, but my fucking mp3 collection is so unorganized it's kind of fucked. No worries, as it seems that it'll be easier to fix on the actual unit or the software shipped with it then it would in windows explorer.
The only real problem I'm going to have is album art. It's easy enough to get on there, but a lot of my ripped albums and such don't have an actual .jpg in the folder on my PC and I can't figure out where the album art for the folder in mymusic comes from (show hidden files and folders is enabled). Does WMP keep them all in a standard database?
