" they have essentially no commercial competition"
Yes I know the reasons for that. I was trying to point out the consequences not the reason. The fact that most of the world has managed to lock itself into a very unhealthy situation bodes very badly for costs and innovation. Even Trevor is suggesting giving MS even more money ( & power of course) in exchange for a few crumbs, admittedly crumbs he wants.
I don't know what can be done about it in the short term other than the change to mobile devices and a much healthier mix of OSs - I'm just glad that me and mine are completely out of it.
