Zune is awesome
Two major issues and one minor issue...
Minor issue first: There is no play all option for music in my collection.... (yeah you can "ctrl A" and play but WMP has it so why not zune?)
Now the major issues... Without a zune pass (or possibly internet) the entire software is gimped for general use, even searching for media in your collection searches zune as well and don't get me started on the *pinned* bands, it took me a while to work out why it took forever to play a song I clicked on before I realised it wasn't in my collection but on Zune pass...
Second major issue... Video. First I'll start with the good bit, the ability to stick videos into series and types is brilliant, something I've wanted to do on WMP for ages but never found out how... However, and a big however, why is Zune so picky on what it will play? Half my AVI's were automatically stuck in its album, no fuss, the other half are apparently invalid file formats, despite being avi's like the rest and playable in WMP.
Thought I'd stick it in here as a few people may have had issues with this already. I was thinking I may use it instead of WMP as it looks really nice, there are just too many issues (as described above) for me to do that at the moment though...
