I have a mid 2010 MBP, 2.4GHz running OS X Lion. When I upgraded from SL to Lion, it was about 3 months before ML came out. I haven't heard much about the version after ML and I'm thinking of upgrading now. Would this be a smart move or should I just wait a few months? It's only $20, and I don't think I'm missing any exciting features that I need, but I do like to stay up to date. Also, would it be best to just do a direct download and install or a clean install? I tried searching and nothing really came up, which is weird because SL to Lion threads were pretty much all I found when I last upgraded.
