No, I decided not to bother with it. I use this computer for uni and work so I can't go down to my local NextByte or call up Apple (no Apple stores in Tassie

) to arrange to get the light leakage repaired. I've done some searching in the official Apple support boards and a number of other Apple/Mac enthusiast forums and have found out that Apple have this problem right across their range of aluminium iMacs (2007-2009 models) and that even their own showroom iMacs exhibit this flaw too. Sending it in to fix it may actually result in more problems too. A number of people on EVERY forum I visited complained that when they received their repaired iMac they noticed a small amount of broken pixels, light leakage in other areas of the screen and even light leakage RETURNING after a period of time if their repaired iMac had no additional problems once it was returned to the owner. I've seen pictures posted on some forums that showed much worser light leakage than what I have. In fact I would probably call my little problem "mild". It's not off-putting and I hardly notice it day to day except when I use Front Row when the screen is black and the room is dark. The problem may get worse over time or it might not. I don't know. But if it does then I'll have to buy Apple Care to extend the warranty and get it fixed IF I ABSOLUTELY MUST DO SO.
But just out of interest to those who have sent in their iMacs or other Apple computers
that are still under warranty to Apple or NextByte (with or without Apple Care), is there any price involved?
