Its just an improvement over the previous desktop manager. I like the UI a lot better and it is faster with syncing, backups, and media transfers. It is definitely worth upgrading.

Well it looks better, but it gave me alot of connectivity issues where when I connect my BB, it would sit there and scan for the apps on it forever....nothing happens no matter what I did......back to 5.0.1
