GuitargodGT, biggest hole in Windows security you're going to find is Internet Exploder. Second biggest hole in Windows security is basically that its default security settings are basically a big glass display case that says 'Please don't smash the glass with this hammer conveniently placed directly over the glass and supported only by a small arrangement of twigs and mud that could very easily be disrupted and cause a catastrophic failure even if you don't mean to'.
I agree that we should be arguing Windows vs Mac OS because the only beef most people have with PC is the fucking operating system - apart from that, you have so many more options because there aren't legal protections to fuck and back on the licensing of PC hardware, you're able to tweak a hell of a lot more because Macs do also suffer, on occasion, from the 'protect the user from functionality that he may use to blow the computer up' syndrome, you don't have to worry about anything running non-natively on Intel (you know, that FUCKING PROCESSOR THAT WASN'T THE ELECTRONIC EQUIVALENT OF 'LET'S PLAY PAINT THE TURD!'), et cetera - and the only thing still going for Windows is essentially inertia.
If Vista is only a third of the bitch it's supposed to turn out to be, solely judging by Microsoft 'fact sheets' and even the nicest of inside testing, it's still going to be the computer market equivalent of napalm in the playground and it wouldn't be surprising to see it eventually divide the camps into 'I'm going to fucking Mac/Linux/that dusty slide rule' and 'I'm convinced that no matter how ridiculous and dysfunctional this turns out to be it'll still be in my best interest to keep using Windows because... durm, well... I'm... already using it, and so are a lot of people, so it must be right'. It looks like it'll be a cross between Big Brother and Bubble Boy when it comes out if any indication may have been given by any product testing seen up until now.
Again, as I always do because I'm an obsessive bastard and somewhat of a computer nerd, I'd like to take this opportunity to say that Linux has all of the stability you get from Mac OS (and then some... keep in mind that the reason OS X is as great as it is happens to be that it is UNIX-type) and there's a version for any PC/Mac/toaster oven that you may already be running, it's free, and it doesn't treat you like a fucking baby who can't understand basic computer operations like its competitors seem to.
