At first, I was interested in getting a 2.0 GHz 15.4" MacBook Pro and upgrading to the 2.16GHz processor, 120GB HD, and then later buying another 1GB stick of RAM later, but now that the 17" has the processor and hard drive already upgraded, all I need to do is buy the RAM, but God knows I'd like to pay less than Apple Education's $270 for it. I've looked at MacMall.com mainly, but I was wondering if there's any superior brands to look at and also if there's only a certain "type" to look for. I don't know much about RAM. Also, should I install it myself or could the guys at an Apple Store put it in for me free of charge (maybe if I complain about the computer hum?)? Thanks! Daniel.
