Anyway, just for the sake of balance:
"It just works - all the time." So does Windows.
"It doesn't start to slow down after 3 months." Neither does Windows. My current install is going 1 year or so with no slow down that I've noticed.
"Software doesn't crash." Neither does any of my Windows software. The only thing I've had crash is Firefox due to shitty websites. And QuickTime when I used that piece of trash.
"Software available for the kind of development I do is far superior than what is available for Windows." There's more software available for Windows - bar none. Not sure where this one's going? TextMate? Dreamweaver?
"I don't have viruses or spyware to content with." Neither do I. No viruses or spyware that I can remember in the last two years.
