I wanted to post this because *I* think it's interesting, and because it might be useful to someone out there. At the same time, I don't mean to start another huge discussion about problems with the new 15" al powerbooks cuz I guess that stuff is sort of old news. But at any rate... I got a 15" 1.25 ghz powerbook about 3 or 4 weeks ago - whenever it was that they first started arriving. Right away I noticed that it was making a really weird clicking noise. I think it was the hard drive but who knows. There were several threads about this noise, I think. Also, it was really hot and the fans went on all the time and made a huge amount of noise. Since I had nothing to compare my powerbook to, I coulldn't tell whether these issues were normal or not. Mostly I was concerned about the clicking sound, it just didn't seem normal to me. I was very torn about what to do - I didn't want to complain to apple and make a huge deal about it if it was normal. I ended up sending the machine back, partly due to the fact that I was also having a problem with the track pad. I finally got my replacement yesterday and what I wanted to share with you guys is the fact that this new one is *clearly* different than the first one. I haven't heard a peep out of it - the hard drive is silent, its not hot at all, and the fans have yet to turn on. I just thought this was interesting. Sorry for the long post.
