I want to add a gig stick ofram to my 12 inch powerbook which brings me to two things 1. What kind of ram would you recomend/have you used in yours? I have seen alot of people recomending crucial is that the way to go? 2. I tried to unscrew that door on the bottom the other day just to check it out but those motherkers are tight. Then got to wondering are they reverse threaded or regular? Any other advise you have for me?
