First of all, I thank you all for any and all comments! I'm ready to order this weekend. After much consideration I'm thinking I am going to go with the 27" quad, but that extra $300 keeps me thinking... Ready to order ASAP once I figure out what I need. I am coming from a part-time year-old macbook just too small for me) and doing away with PC"s for good! 1. Basic "every guy" computer useage 75% of the time. Basic internet, word processing, and photo editing. 2. Will do basic home movie video editing with iMovie or similar. 3. I do work with GarageBand heavily on occasion/spurts, but nothing too intensive (yet). 4. I likely won't run too many other apps/programs other than iWork, Scrivener for my neverending/uncompleted novel, and YoJimbo thingy program looks like it might benefit me as well. But, surely I'll find a few more programs I'll end up with. 5. Never any games, unless they are the very basic stock-type games that come on systems. 6. Oh, dare I inquire about the trojan thing once again? I about got whooped the other day asking the same old:>) I know I have to "allow it", etc. My concern would be say I pay for a download for a program and allow it, how am I to know if there is something bad hiding in it? I just want myy CC# and paypal info protected. I'd prefer not to run any virus/trojan/keylogger stuff (again, sorta lost) but surely will if truly needed. To my concerns, help me make the purchase! I'm all set to go for the 27, but still ask myself on occasion if it would just be too big. I sit approx 2' from my monitor 99% of the time. My current display is 22" and is fine, but seeing the 21.5 against the 27 in person did it for me. I work with the last 21.5 base version (right before they came with the wireless mouse/kb) with my students. But we aren't doing any in-depth GB or video editing. FWIW, I love that machine, as well as a few very old little white iMacs that are still going strong with all the punishment they get! Will upgrading RAM to with 8gb option be beneficial for my needs? And alas, duo 27 or quad? So basically for $300 more I get the Quad and better graphics, correct? Numbers and tech data are useless to me, as I'm clueless. I've never understood the video card option as well, so might as well throw that all in this big mix and be done asking questions all over these boards and making people mad with "the same old questions/save bandwidth and search, etc". I truly appreciate any help or real suggestions, as well as your time. I've learned and researched this on here for a few months now, but the time has come! Basically, duo vs. quad for my needs, any of the rest is icing on the cake if you'd care to be so kind to humour me Thank you once again.
