I personally think that computers are now really nothing more than appliances.
In the 'good old' days they were great fun to tinker with and hack and improve upon. I think they've reached a level where 99% of people just want a device that will allow them to browse the web, look at photos, watch videos, etc...
So it doesn't really matter whether you use a windows/mac/linux box - they all do the same thing.
Now, back in the 1980s things were different - it was a brave new world, much more fun and much more true innovation happening. We've reached a plateau now.
