If that has been done, then I apologize. I feel as if statistics should be done on all this MacBook Pro mess. I think that this could be a valuable resource to discover who actually has problems, if it is random, or if it is specific (which it most likely is not). List your size, week, speed, then say what problems you had originally or presently have and whence they come (as in processor or monitor). As in: 15"/week13/1.83ghz/whine(monitor),heat or 17"/week1/2.0ghz/none Please, everyone respond whether or not you have problems because I think all mainly want to see who does NOT have problems.
