VERY good artical. It explains alot of what I feel. I did't switch from windows to linux because it was the 'fad' of the month. I made the switch because Linux and OSX IS superior as far as over all products go.
I also used to be quite the fan boy when it came to windows. But that short sightedness changed when I just got fed up with the constant reboots, bad software and constant expensive upgrades.
As far as portable devices go. Well I know that most cell phones run their own java applications and are hardcoded. Most of them, too, would probably run some sort of embeded Linux OS just to keep over all cost of the portable device down.
Thats not to say that windows doesn't have a purpose in life. Its purpose in my eyes is the continuing infection and carrying of viruses and trojans to unsuspecting users, quickly and easily!
Windows was never built for normal computing in mind. It was built to be 0wn3d!
