Hello All, I'm new to this forum and to the current generation of MACs (I had one of the first MACs years ago). I am a computer professional who was forced to use Windows by my employer. Recently some of the requirements by my employer have been relaxed and I have gotten the urge to own another MAC. I have used this and other MAC related forums to do research for the past couple of months and was just about ready to pull the trigger until I started reading about the problems with the yellow screen and other quality related problems. I realize that the vast majority of people come to forums to either help, solve a problem, or complain. I'm wondering just how serious these problems really are and should I postpone pulling the trigger on a fully loaded IMAC until some resolution has been reached?
