Yeah, like the others said, this is old news, so meh. But seriously guys, marketing is marketing. Take it for what it is. A lot of other companies do similar things (ever seen car commercials? They're always claiming that the competition sucks). Somebody might say "But Microsoft doesn't do it!" Yeah, and they also hold 95% of the market. They barely advertise their consumer side of stuff as it is. They really don't need to. Small companies like Apple tend to do this kind of advertising. The idea is to break into some mindshare by pointing out your advantages over the competition, rather than just showing people that you have a product, like Microsoft does. The difference with Apple is that they tend to overdo it, being creative, as they are. The company that has the majority of the market doesn't need to advertise like that. If they did, that would suggest insecurity.
Honestly, I wouldn't complain so much about the Mac community. On the face of it, sure, there are a lot of zealots. The PC community is the same way, and honestly, I hate the loudmouth idiots on each side. But it's not all bad, and that's the case with most things. If you can get into a Mac forum, there's usually a bunch of cool people in there somewhere, and while most of those people believe to some extent that they're using the better OS, most Windows people believe the same thing about theirs. I've been sitting on the fence for a few years until now (both PC and Mac since 2002, finally sold my A64 for a new Core Duo iMac) so it's kinda opened me up to noticing this stuff more easily.
And please guys, don't be stupid. Preference as to which is better is just that -- preference. You can't just make blanket statements about this stuff without looking ignorant. Each one has it's strengths and weaknesses. OS X tends to be a lot more straightforward to use because Apple has very strict UI guidelines, Windows tends to be more popular because it has a larger game base (although the Mac has been catching up rapidly in this, usually only being 4 months behind on some games -- better than the years of before) and because everyone wants to develop for the OS with the largest share. The only real problem with being the big guy out there is that plenty of crap code gets written, and viruses and spyware, of course. And yes, you can avoid it. But, OS X does have something going for it with security through obscurity. That and I haven't seen much malicious unix code out there...
Yeah, and about that Intel vs. AMD thing. Just take a nice look at Yonah. Intel is making a turnaround. And if you still think Macs are slow, you haven't used a G5, and most definitely not a Core Duo Mac.
