Exactly, if its not broke, why throw more money at it. I don't blame you. If I wasn't able to get my hands on dev copies of XP, I wouldn't be paying for any OS, so it would be Linux for me. I telnet to Unix computers quite frequently at work, and I write software that is marketed for Linux clients, so its not like I'm unfamiliar with it, but I just don't get into the whole religous anti-M$ thing. I like to be able to play games that require WinXP and the PCs I have were already some version of windows, so the upgrade was easier. But you are right that Vista looks too locked down at the moment. But what's the rush? Wait a year for all the patches to be released and cracks to be figured out.
M$ was late into gaming, but wasn't Sony just trying to bite out some of Nintendo's market? Wasn't Nintendo trying to get some of Atari's? Is SanDisk and every other iPod copy just trying to get a piece of the pie too? But really, the XBOX was THE best computer you could buy at the time. Anybody could flash the BIOS and put Linux on it and do whatever with it. The 360 has lots of good things about it, too. I don't think you'd be turning on a PS2 any more often if you had one.
Last I heard Gates was evil, yeah, but he also donates HUGE amounts of cash to charities (I have no comment on my boss.) I was in San Fran during MacWeek. There's nothing more pathetic than a bunch of nerds circle-jerking while Steve Jobs gives a speech on another new gadget that has an 80% chance of going nowhere. Hockey Puck mice? Mac Cubes, anyone?
BTW, I'm on FireFox because its safer and way more configurable. But if it keeps on hogging my memory like my SXR guzzles gas, I'll switching to the next most stable and secure platform. Its all about functionality vs. cost for me.
