So your idea would be to buy a rMBP(or cMBP) , buy a better SSD, install it myself ? Cause I know for a fact that the rMBP is quite a bitch to open, and to change parts in it must be a nightmare. So I guess you're referring to the cMBP.
in my opinion 16gb of ram is overkill, unless you're a big shot editor or something.
btw which laptop are you referring to wit the "(1 Tb HD, 256 Gb ssd, 16 Go RAM)"?
About changing storage: did it with my MB 13'' (2007) it was pretty simple. this time around I just need to the entirely computer
So which SSD would be better and cheaper?
is there a huge difference in performance between the i7 in the cMBP and the i5 in the rMBP?
