Yeah, that reaaly surprised me when I found out- on the wiki.
There was no warning about it being beta when I downloadeed or installed. I thought I'd get a "heads up".
I've had it for 3 weeks now and don't want to give up all my bookmarks, downloaded videos, Tuts for blender, documents...etc.
Only 2 months for it to out of beta, I think I can hold out...
