Hi all, Can anyone give me your personal thoughts on the 20" iMac? I'm currently using an old Powermac desktop (It's a 4 -1/2 year old, dual 1 Ghz Quicksilver). If the Intel switch wasn't around the corner, I'd have a new desktop already. My main work is in Photoshop, Illustrator, and occasionally some 3D programs. Anyway, I was thinking of getting a 20" iMac to hold the fort while I wait. Would I notice any bump in speed for graphics programs? (My desktop has been reliable but occasionally quirky). I'm also considering using the 20" iMac after it's out of date as a TV or as a display at exhibitions to show video or Flash movies of new products. Any thoughts would be appreciated!
