Hi, long time lurker (and really, you guys are awesome -- what you write is invaluable) who just created an account because I need your help -- My girlfriend & I just moved in into an apartment together. I work from home as a software developer, and she's an architect who uses the Adobe Suite a ton, and we figured that the 27" iMac would work perfectly for the both of us. The problem: all of the forums and discussion boards about the black spots, smudges, and dust that form inside of the 27" displays. My question(s): for those of you that have owned a 27" iMac for at least six months, how many of you have encountered this? How many of you haven't? If you haven't, are you doing anything in particular -- like dusting around the computer every day, or using dehumidifiers -- to keep smudges from forming? I would really love to buy this computer, only I'm a bit terrified that I'll have to lug the thing back to Apple every six months to get the display pulled apart and cleaned. Apple Care is a no brainer, but still -- for a computer costing this much $$$, I'd hope that they would have solved this by now. (I'm also hoping that I'm just reading about all of the "bad luck" cases, and that there are plenty of people with great experiences with their screens.) Thanks!
