Anybody have any experience with MBP refurbs? I am specifically interested in knowing whether Apple has been able to solve some of the issues that they had with the models they are (still now) shipping: heat, whine.... If so maybe it makes more sense to pick up a refurb as the problem will have been addressed rather than an new machine! Otherwise, as I need a machine soon (prefeably a laptop), I may just pick up a cheap mini until all of the quality issues have been sorted out (rev B next year....). I could afford a MBP but not one with quality problems and I can't stand noisy machines. Any advice?
