I want to buy one, but I am not sure if it's abilities are limited... I know if I go with the MBP then I can for sure but if I can just do what I need with the regular MB I wanna do that. I wanna be able to video edit movies that I make... Generally 1-2 hours in length.... I don't really need to be able to do special effects or whatever... What specs would be good for this? Also, I have never owned a Mac before.. What software should I buy with it in order to do this? Thanks...
