Finally decided on which iMac I was going to get.
At first, I wanted the fastest 21.5" they made.
Then I wanted a 27" i7 Quad-Core.
Then I wanted a 24" refurbished iMac.
I agonized about which one to get.
Then I went and got the fastest 21.5" they make currently.
The three monitor set up is cool, but my G5 iMac might have to find itself a new home. I'm sure someone can think of a better use than just using it to watch streaming Netflix video.
Maybe set it up as a server, or a workstation for the wife, or something. I can think of worse problems to have.
