We have a massive 2.1 catch-all thread you might want to give a peak at. I try my best to keep everyone posted on what is happening with development, and there is a ton of great discussion over there.

And the Nexus wallpaper hasn't worked yet since the port. I know it is bugging a lot of people. I don't really care if it works or not, but it has definitely piqued my curiosity as to why that one won't work when all the rest of them work fine.
Just some food for thought, but if you are already using 2.1, then why go with the official release when it comes? I say this for two reasons... First is the fact that the official release will kill your root. Until someone figures out how to root again, that would be that. Second, by the time the official release comes out, I am sure the people who are working on the ROMs now will either have this one running 100%, or they will be stripping the official release to patch the bugs with. In either event, in my eyes anyway, it would make using the official ota pointless.
edit: Ninja Merge!! lol.
