Hey, if you have the kind of money that medical companies spend on testing and stability, and you want to spend that on Linux desktop environments, I won't complain. Although it probably is better to spend that on developing life saving devices than it is on fixing outdated desktop paradigms.
There are competing paradigms now, and that is good, but they have not yet actually reached use value and productivity levels where it is appropriate to say the desktop paradigm is out of date.
At the worst, both will become more generally flexible to keep their value to the users.
