Mac and Linux both OWN windows in secureness(don't give me that shit about it's because nobody uses it, as that is the opposite. First off, Linux has SELinux, which is the equivalent of Adolf Hitler destroying the trojans, and both Mac and Linux have a Unix filesystem. The Unix filesystem pretty much means that you MUST be the user or root to write to that users files. There is no exceptions. If you are not root, you cannot edit system files, period. No trojans, nothing.). WIndows sucks on EVERY level. The only thing good about it is that there are decent apps for it, in which is not windows' doing, that's the application writers.
