Yeah, I forget the exact version I installed, but it was one with Gnome3, something that I thought looked slick, and would work great on a tablet, but it ate up too much of my precious screen space (netbook). I didn't have any real issues with it besides that, I don't think it came with gcc though, and I prefer apt to yum (but that's just preference).
So here's my plan, backup all my junk to a HD, then format everything. Partition up for two OS (arch and LM) and one for home. I'm really excited to see what's new with LM12 (not sure if I should get the classic one or debian based..?). And arch will probably kick my ass but it'll be fun.
