What's your point??  If you want to be stuck with a deficient operating system, then fine; just stick with whatever MS puts in the box and then hope and pray for a continuing stream of timely "updates" (fixes) to correct problems.

OTOH how hard is it to download a file and click "install"?

Your analogy is flawed.  If you buy a car, do you go to only one dealer?  Did you always take one on the lot or have you ever ordered one with options you wanted?  When you got the options you wanted, was the car any more difficult to drive?
