hi there, i just joined and this is my 1st post. i got a macbook around this time last year and iv been in love ever since, it has 2 gb of ram and 1.83 Ghz intel core 2 duo processor. iv noticed that with the new macbooks the ram can go up to 4gb, while around the time i bought mine it could only go to 2gb, i was thinking that the older macbook, that i have, wasnt able to hold 4gb of ram, so i thought id ask here to make sure. so if i put in 4gb of ram will it work fine?? sorry if its a silly question, just looking for clarification. thx in advance.
