I have the latest 24" iMac that came out before latest change (27" model and the 21.5"), It is just over 4 months old. The screen started to get dirty in the middle, just below the iSight camera. I removed the glass and tired to clean it without luck. I would likw to replace it, here are my options. My setup is like this. I have the Mac on the lest side of the table with an external hard drive and external burner to its left. I have a 24" screen to its right which is connected to my gaming PC, it stands right side of the table. So it is MAC Monitor PC. To the left of the Mac is my TV which is around 2-3 meters away. My first option was a MacPro but i am limited with space. I would have to go with either another iMac and hope i dont get the same problem or a fully loaded Macmini. What i do on my Mac is a lot of video viewing, torreting, iTunes, some video converting and a lot of CD/DVD burning. Basically everything except gaming. I would really like to get an iMac but the chance of it having screen problems is high (my friend has an iMac with the same problem). I am really lost here, any ideas? Thanks in advanced.
