over the past week, after the graphic issue was resolved I encontered some annoyances that became issues: -my speakers rattle like crazy which muffles and obliterate the sound quality when playing videos on youtube, or listening on itunes, or editing a video in final cut pro! the system volume level is 8/16.... the mac bong startup sound rattles it... as usual the popping noises gets worse when playing streams of audio files in final cut pro.... -there's a terrible light bleed, crappy viewing angles and stale colors ( I prefer the warmer 9c99) -and finally, my superdrive went south after failing to burn 5 dvd+r dl properly and they are verbatim burned at the lowest speed so how should I convince my applecare rep to do a exchange? I'm within my 14 day policy... If I do get to exchange it at a apple store, which build week should I get? I have a week 11 and wondering about a week 10 or 12?
