My predictions for the next thirty years: OS X will gain further dominance as Windows fades out and its technologies get absorbed into Linux, while PC manufacturers slowly put Ubuntu or similar onto their machines, and the choice becomes largely OS X for rich content and Linux for lower level computing. Eventually, however, Linux will catch up with OS X and become a serious platform for Adobe, Microsoft and even Apple at which point high end PC manufacturers will start customizing the appearance and functionality of Linux so as to distinguish themselves from one another in a way never possible under Windows, hence providing a renaissance for manufacturers such as Sony. At this point Apple will start to get left behind unless they follow suit and become PC manufacturers and software developers for Linux rather than OS X. It will be like Apple's programs for Windows in reverse - not designed to attract users to OS X but to ease the migration of OS X users to Linux. Unfortunately the hatred for OS X users among the Linux community will resist such measures, and Apple will be left flailing around. By this time, Microsoft will be a respected organization again and the OS wars between Windows and OS X a distant memory (similar to Britpop). Apple will spend the next thirty years trying to regain ground programming for Linux and making high end hardware. But in the meantime the OS will be slowly becoming extinct altogether. Programs will eventually run independent of OS.
