Jesus. H. Christ!
My iMac came back from the shop today. Fresh install of leopard, new bezel, new iSight board, and it was teh snappeh™. I put my 112 GB some files on the HDD. It instantly slows down. Like a LOT. I open iTunes, no files. I reboot it to see if that would help. No Alfred, it did not do the ancient Mac crash sound, but it would not freakin' boot! Just sits at the boot screen.
2 hours after being home.
2 hours.
I'm formatting the disk now and installing Tiger.
I swear, if Apple doesn't get their dang QC under control, there are going to be a lot of funerals that didn't need to happen.
