Hi everyone, I know that this is a known issue but I have a 2.66 MBP 15 inch i& with 4 gb of ram and a 7200 hard drive. At least a few times a day I am getting the beach balls for around 10 seconds at a time. I am only running things like Skype, Safari and iTunes. It is really bugging me to get this on a machine of this spec. What do you think I should do? Would Apple repair or replace the unit?
