Got a white C2D white (jay leno) 20" 2.16 imac, and upped the ram to 3 gig last week. Got it new in the box for $990, hooked it up to my 22" lcd, and was able to put applecare on it.
Saw two days later that they had the refurbed 20" alums for $9 bucks more, plus tax. Was starting to have buyer's remorse until I got on these forums and saw the relatively minor differences between the two models.
I don't do a lot of high intensity stuff with my mac. I make and review documents, so the dual screens, ability to magnify them, and matte panel make life easier staring at the monitor(s) all day. I was on the internet checking county filings and dockets. Occasionally I'll rip and burn a movie. The difference between parallels on this machine and virtual pc on my dual g5 is night and day for the one or two windows applications that I absolutely have to use.
Yes, I could have stayed with my powermac a while longer, but I was able to sell it and have that cover most of the costs of the new machine. (I like having applecare on my primary system.) My current one is technically last week's flavor, but it serves my needs well. I anticipate it doing the same for some time to come.
For the people who absolutely must have the latest and greatest models, they'll have lots of opportunities to do so with the intel roadmap. For the more budget conscious, there's plenty of opportunities of discontinued/refurbed models at the online apple store or even the local best buy. I'm grateful for a) craigslist, and b) the fact that you can transfer applecare. And chances are, none but the most determined power user will tell the difference between the machines.
Isn't this a great time to be a computer user, and a mac enthusiast?
