The way I see it, the biggest threat to OSX is Linux not Windows. The PC world seems pretty obsessed with Linux as a potential saviour from the tyranny of Windows and all its failings. It's not that they're anti-MS per se, as they seem to think all they need is Office for Linux and the puzzle will be complete. Ha! Yet, here's OSX, like Linux, Unix based and so is not susceptible to all Windows' problems, especially security. It already has MS Office and many other tier one applications (eg Lotus Notes, Adobe Photoshop et al. Macromedia Flash et al etc etc etc etc). It has many applications that are popular on Linux (eg Apache, Squid etc). And it has a MS owned Windows emulator if you really do need it. So why do the industry scribes keep harping on about Linux??? Why are they blind to OSX which is way out in front of Linux in terms of being a true desktop alternative? Although it would upset the Linux community, in the longer term it would benefit them because for developers porting apps from OSX to Linux is significantly easier than from Windows to Linux which means it's much more likely to happen. I think it's time Apple started promoting OSX as the answer for those waiting for Linux.
