I really need to get a new laptop in the next couple of days, because my IBM Thinkpad is about to kick the bucket, and I was thinking of making the switch to Mac and buying a MacBook Pro. However, a little Internet research revealed all kinds of complaints about random shutdowns, overheating, weird fan noises, uneven screen brightness, etc. I know Apple released some kind of firmware update that was supposed to address some of these issues, but I also saw some suggestions that this didn't fix the problem adequately. I was wondering whether the community here knows whether these hardware issues are still present in the present lineup of MacBook pros and/or if this firmware update fixed all these problems. I read some pretty hellish stories about MacBook Pros shutting down constantly and overheating and consequently being unusable, and I am concerned this might happen to me if I buy now. Thoughts? Oh, will the answer be any different if I buy a 17-inch MacBook Pro from the previous lineup, i.e., the one that's only 2.16 GHz instead of the new 2.33? I can get the older 2.16 GHZ 17-incher for a thousand bucks less but am concerned that since it was produced earlier, it might be more prone to these problems. Does the firmware fix also fix these problems on this first-generation MacBook Pro? Thanks.
