the 4 year imac thread brought up some interesting points about how much life you can expect to get from a new mac, and how much it costs per year, factoring in upgrades. I have a late '08 C2D 24" 3.06, 4gb, 500gb 7200 rpm, the screen is perfect, it works perfectly, even with daily full time use. I have to admit, I only use it for the most basic functions, other than one season of Garageband mixing. It's mint. I am interested in selling and have seen one or two just like this sell on ebay for close to $900. (free UPS shipping, and "Office" included) One seller posted that 7200 rpm was a upgrade or bonus for that model; same as i have btw. It's fast, but i also pay extra from my provider for what they call "Turbo" internet booster...heheh. I got a Macworld flyer today for a "sell your mac" vendor who claimed top dollar... $380. and that's with clicking the "like new" button (just to see). $380? Hell I'd rather give it to a family member or friend! I've looked at a couple sites that sell used iMacs and figure my machine on a retail vendors "shelf" runs about $1,100. I may be wrong as i haven't spent a lot of time checking this out, but it gives you an idea of how confusing this can be. I'm just looking for comments, insight on this issue.
