How many of you have had experience with all of them?

[True Dough]

1. 0.2%

still clinging to MS-DOS! Godspeed, my 1990s brethren!

3. Loved DOS. So nitty gritty.

There are probably still some legacy instruments/utilities runing old small DOS systems without available updates.

2. That's neat

I found myself pre-guessing future outcomes when the good and bad players kicked in. No surprises, except I expect the Apple OS systems to grow bit higher.

4. this is installed base and not counting ALL computers

mostly embedded computers that are in everything from your car to your fridge.

A better measure would be either be computing OP/sec/per OS... or user interactions per OS.

Linux would be waaaay ahead ( most of the web is powered by Linux servers ).

I have written software at the OS layer ( device drivers and file systems ) for most of the OSes on the list. Except for the later versions of Winblows. Even for DOS ( good ol int13! )

They all have their strengths and weaknesses.

Oh, and they didn't count the RTOS that existed during a large chunk of the time covered. I suspect some are still around today.

5. I'm using Linux for the first time.

Me likey.
