Hi I've been seriously considering of buying an iMac, but I have a few questions How is the screen quality on the new 17" model? Has it been improved since rev. A? I remember seeing the old one once, and I thought it looked quite washed out. I know the 20" model would have a much better screen, but what can I do with my limited budget. Right now I'm using a Mac mini, and the graphics performance leaves a lot to be desired, such as iPhoto slideshows, Exposé, genie effect and so on... how do these things work on iMac? And hopefully I get to play Myst V with decent frame rates? (it's pretty hopeless on mini) Thanks for your help!
