Ok, as far as I understand it from reading here and elsewhere, refurbished macs have most of the same rules as buying a new macbook pro- 14 return period from when its delivered, 1 year warranty, etc. (just can't return it to an apple store, has to be by mail). But just checking, fiddling around with the ram in it won't void the 14 day return period, right? Just have to be sure to put the old ram back in first if I return it, I think? I have some extra ram lying around and figured might as well test it on a macbook pro first. Still thinking about keeping it or not, it depends on how my parents feel about it (and whether any news about the 2012 models pops up in the next few weeks too).
