I figure the majority of the challenge is in businesses. And there, changing the Windows adoption rate requires visionary people in charge, a complete set of applications on another platform, and a realistic transition path. I haven't seen a lot of vision in current IT groups; more like, CYA. So it may take a generation or more before enough of the establishment changes to even consider moving away from the current stack of Windows/IE-based enterprise software (the quality of which is oddly irrelevant to many managers). Either that, or a catastrophe so substantial that upper management is forced to start over with IT. Making competing applications on other platforms is technically doable. But, unfortunately, most of the work that needs doing isn't interesting. Years have gone by, and it shouldn't be surprising that people have avoided spending their precious free time developing open-source business apps when they could do something more fun. What's more, with each passing year, the number of new enterprise apps bolting businesses to Windows is increasing (as is their data dependency on existing apps). And then there's the transition. How do you even convince companies to change, much less address the technical hurdles (e.g. different data formats, software bugs) and the user community (different user interface, retraining costs, etc.)? For what it's worth, I really want Windows' share to decrease, but these are big challenges. I do what I can to help. :)
