It certainly is not enough for me. I disagree . . .perhaps in heavy duty video use it's not enough . . .but my 2008 unibody MBP with 4 GB works fine and I typically have a dozen to 20 apps open. It's a bit slower on my wife's older MBP but it only has 3 GB and is stuck with a spinning drive instead of the SSD I have in mine. The SSD is much quicker than the spinner obviously; so mine is perceptually a lot faster than hers but a good percentage of that is the SSD. ----------------------------------------------- There are only three kinds of stress; your basic nuclear stress, cooking stress, and A$$hole stress.
