I am fairly literate in computer jargon, but have nowhere near the technical knowledge of many of you out there. I think i am going to go with the 15", 2.2, leaving it at 4gb RAM (for now) . . . . my question is the hard drive. They give you the option of 750gb @5400 and 500 @7200 (if i remember right). Is the 7200 significantly faster, and the one to go with? If there isn't a ton of difference I'll just take the space but if the difference is noticeable i would much rather have the speed. Is the 5400 a significant bottleneck? Not in the market for SSD (too costly) otherwise i would do that now. I would like to upgrade in the next year or so to the SSD. Any heat issues with the 7200? How bout the screen? Is it worth the upgrade to Hi-Res? I have music (about 2000 songs now, add maybe 25 per month), pics, and various other spreadsheets and documents. I don't game much, but if i do they aren't real graphic intensive or robust games. My wife does some photoshop work, by no means alot though (think 6 hours/month). Spend alot of time on the net. I am probably considered "joe average" computer guy. Please provide any guidance for a Mac newbie. Budget is 2000. Thanks in advance for everyones time and help.
