Thanks for the explanation, but I've written (very simple) Linux device drivers before, I am aware. :) But my point was that you are making a distinction that simply does not matter to the end users that are under discussion. That a hardware manufacturer doesn't produce drivers for Linux doesn't change that, to a user, "Windows can do this and Linux can't."

It's great that you buy stuff that works with Linux. Linux's problem for normal people is that it doesn't work with everything. Windows does work with everything that a normal person is likely to run into and OS X comes pretty close to the same.
