I use my computer in a metal shop and my magsafe gathers iron filings, shorts itself and catches fire. I've gone through so many chargers. I've vowed that the next time it happens, I'm going to mill away part of this laptop's case and solder in a DC barrel jack. So much of apple design is about sleekness and cool factor, not actual robustness or effectiveness. I suppose this isn't the intended use case, but I feel like the use case apple has in mind is unrealistically safe and ideal. And rich.
I still like using a mac, as well as a windows machine and several linux distros. If you have a collection of tools in your tool shed, you want to have all sorts of different tools. Not just rows and rows of the same flat-head screwdriver.
