When i bought my MBP i was in rather a hurry and forgot to say i wanted 1Gig RAM. So im stuck with 512 Mb. Its actually not that bad. Ive watched a film, and had simultanious convos on MSN and iChat (using webcam) and it seemed to handle it fine. However, i would like the added comfort of 512Mb more. Here in England Crucial seems to be a very reputable RAM manufacturer. So i am thinking of buying from them. Anyone got any reasons why i shouldnt? (Ill upgrade to 2Gb matched pair next year when i have money) But for now this is what im going to get: http://www.crucial.com/uk/store/MPartspecs.Asp?mtbpoid=FFC3AC1EA5CA7304&WSMD=MacBook+Pro+2%2E0GHz+Intel+Core+Duo+%2815%2E4%2Dinch%29&WSPN=CT511221 Its a pretty idiot proof system they have, but there is no harm in checking.
