I have to agree completely with barr08. I bought a 20 inch iMac w/ 2 GB RAM and it does everything I need to to do without any trouble. I run a ton of apps at the same time all the time. I use Photoshop on it and it really isn't bad and I know that it will be even faster once the software is Universal. I had a dual 1 Ghz G4 Powermac and was drawn to this when I upgraded cause with a scanner, printer, Wacom tablet, external drives, and everything else I hook into it, I need to conserve space where I can. The screen is nice and bright (actually I don't turn it all the way up cause it is too bright at highest level) and couldn't ask for a more beautiful picture. I don't think that there is a real need to go with the 23" display. Yeah, it is always great to have more screen but it isn't like you are going to be held back by a 20" screen. I am sure whatever you decide you will be happy but maybe by going with the iMac, you can spend the extra money you would save on other things you could use. 🙂 Also I don't think I would worry about the getting outdated real soon either, especially if you are someone who upgrades their systems every few years. I don't see there being anything I can't run for quite awhile with this machine.
