Thinking about buying a 24" iMac 2.8 Extreme... 1. I've heard there are screen issues. Can anyone vouch for this? A lot of stories out there about bleeding and wierd color issues. I plan to buy refurbished so hopefully this is not an problem. 2. Does anyone have experience with running a second large monitor (mine is a 22" samsung) for a dual monitor setup? (im not actually positive that this is possible. please correct me if it isnt) did this affect to performance to any degree? (i will have 2 gigs of apple ram) 3. has anyone heard about a problem specifically with condensation if it is turned off? other than that, if you've got one of these -- post pictures!
