yo whats up everyone, ive been reading this forum for months and decided it was time to post. So this weekend im going to the 5th ave store to get a 17in mbp and i have some questions. Will the apple store take a check? Does the mbp 17" come stock with a gig of ram in the store and i heard they are having supply issues so will there be a good chance of it not being in stock? What is the cache difference between the two HD's?
