hey guys, i bought a 2.2ghz mbp two days ago (now being shipped... cant wait!) and i also bought a 4gb memory package from OWC. the 245$ bill is staring me in the face and, after reading a few threads, i am questioning my purchase. i will be using it primarily for IM, web browsing, hella light gaming (flash... hehe), itunes, possibly some new ilife goodies (switching from pc) and photoshop cs3. many times i'll be doing all of those things at the same time. do you think the 4gb will be overkill, or should i return it and go with the baseline 2gb? possibly 3? i think i want to return the RAM (unopened) and just stick with 2 for a while and see what happens. who knows, maybe by the time i need it (might be going into graphic design... maybe?) it'll cost less. opinions? edit: oh yeah, i'm going to be running bootcamp with windows xp as well.
