My usage of windows over last 5yrs has been as you describe 'a dumb terminal to access a Linux box'. [ A long time ago I was very much into the COM electric cool aid, so have used it as a dev platform commercially, but not recently. ]

To be fair my use of OSX over the last year has also been around 50% 'dumb terminal' due to web work.

I just never see people hacking on windows laptops anymore, and on balance I think its a good thing.
