Or should I say "downgrade" to Lion? - just a question, since so many people are complaining about it. Well, I just want some advices. Anyone? Since I have this macbook pro (same year, same specs, same graphic board/adapter), this is my only concern. I will install using a flash drive (clean install) and keep my SL DVD beside my laptop. If ANYTHING annoys me, I wont hesitate to return to SL.
