After using GAIM 1.5 all this time, and trying 2 a couple times earlier this year, I have made the complete move over to 2 now. I'm lovin' it, especially since AutoProfile was updated to work with the latest beta now too. It's smooth sailing (just about) now. Hopefully, nothing breaks from here on out.

Gaim 2 is great, I switched over to it not too long ago. However, things like file transfers and direct IM connections haven't been working too great, and Japanese support is a pain in the ass to setup (I still haven't been able to). I'm not going to switch off, but once they polish it up, it'll be an awesome client.
