Re: it's the os...
Mac OSX - the best option of the bunch - imho.
Pfffft..... what a pile of shite. osx just happens to give the impression of stability because of the limited hardware it is made to work on.
the only reason why linux will never be ready for prime time is that you need a certain level of know how to administer a Linux box.
any idiot can use OSX and not break it, but underneath the polish is still unix.
windows, love it or hate it for whatever reason, its the standard desktop environment, and will be for a long time to come.
