I am basically confirming the the obvious, the 24" is the obvious way to go if screen estate is your issue, or a 20" +monitor. As far as quality, the 24" iMac S-IPS panel views much more colors, and its much more vivid (before i calibrated the 24" imac last night, now that ive done so with the Spyder2PRO, it beats the 20" imac in every way) but on topic the 20" iMacs TN panel is a really big put down, and the viewing angle actually wasn't as bad as I've posted before, aparantly, one of the panel's apple includes in the 20" imac isnt really horrid, and we got lucky, but some panels have really bad viewing angles, but I can tell you, the 20" imac on the default aurora wallpaper wasn't as pretty as the 24", even in same lighting, some areas of the screen were washed out on the 20". But to my surprise, the 20" imac didn't feel small after 4 months of me using my 24" imac (20" is my dad's office computer at work), the 20" imac was very spacey, and well, HUGE, it seemed much smaller at the apple store, i can almost see no difference between the 20" and 24", both have nice big screens, and im comforable with both. So if thats your issue, the 20" isnt "that" bad, making its issue "untrue" color, and maybe the bad viewing angle. either way, they are both nice imacs, the 20" imac has 1gb of ram unfortunately, mine has 2gb (it says 4gb in the sig cuz i ordered 4gb), and well i didn't really see a difference, i guess its cuz we ran software update, installed omnifocus, bento, and iwork onto it, today it left for my dads office at work, and the 2.4GHz was very speedy, so maybe the extra bucks for the 2.8 may not be worth it, but if you do video encoding a lot (not necessary huge projects), or if you have tight schedules (like me), quick encodes can be done to large projects.
