That is true Gorgonops, I should have mentioned that as well. I've certainly seen these machines with this issue. My own fortunately did not. (Yet, I still have it and would like to replace the hard drive and find a use for it one of these days...) Luckily Apple is usually pretty good at identifying weak spots like this and fixing them. Again, I think the MagSafe power adapter is great. There have been quite a few times I've accidentally caught my foot on my current power cord and it's just unplugged without breaking anything or dragging the computer off the coffee table with it. I'm trying to be more careful, I swear.
Back on the topic of the PowerBook G4, I also managed to break off the little screen latch somehow. Not sure if that's as common of an issue as the power adapters, but I'm throwing it out there. Not too big of a deal, after that I'd just turn it off to travel with it instead of putting it to sleep. Another design change for the better in my MBP, actually.
All minor things that can be avoided with care. Or in the case of the power adapter, replaced with a cheap aftermarket or used one. I stand by my comments that I'd like to bring my 12" 867 back to life and score myself a larger 1.5 or 1.67 in nice shape one of these days. I agree with gobabushka that you'll love it.
Reading your signature I don't see a laptop in there, so if it's your primary portable I think you made a good choice. The 17" is too big for my personal tastes to carry regularly, and while I loved my 12" for being small the 15" widescreen is nice for the extra screen real estate while not getting too big. That's all personal opinion so I respect anyone's argument against it.
