The correct counter to that is to point out that in no wise was DOS an 
'operating system' - it was only a program loader.

In fact you could entirely bypass it to write directly to the hardware 
and many industrial applications did exactly that, yea even unto running 
their own multitaskers  and so on.

concurrent CP/M was about the smallest multiuser multitasker OS that was 
ever crammed onto an 8086 platform IIRC. Or there might have been a real 
time one or two  as well.

Linux by its nature sets out to be an unrestricted UNIX like system,. 
complete with all the complexity and bells and whistles needed to have 
multiple users, multiple processes , interprocess communications, 
daemons to handle single thread hardware like a disk, multi-layered 
security, and the ability to intersperse drivers in a rigorous manner to 
access arbitrary hardware.

In short it is a complete multitasking multiuser general purpose 
operating system and you simply cannot compare it with DOS.

SCO Unix needed a 386 to run - only Venix IIRC ran off a 286 - badly.

It was extremely successful because it actually worked. At an affordable 
price

I've seen 256 users  via serial cards running on a 386 running SCO. 
Extreme, but possible, but 64k users was a more normal limit with 32 
being normal.

We ran about 150 over telnet at one point once the TCP/IP worked....:-)

This was PDP/VAX territory ...at a price people could afford.

can avoid it; the new culture tells us you should always take offence if 
you can. There are now experts in the art of taking offence, indeed 
whole academic subjects, such as 'gender studies', devoted to it.
