Well, the OSen I quoted RSTS, CP/M, Flex09 and contemporaries on small 
minicomputers and early microcomputers, are all single tasking, and all 
had worse display handling than the smartphone OSen, because they all 
were basically green screen 24x80 systems. 

In my mind the improved graphical interfaces of the early smartphones 
(and even on the Palm Pilots) puts the latter ahead on points, and if any 
are multitasking then they're streets ahead.

IIRC first small and cheap multitasking OSes were: 

- Microware's OS/9  in 1981, so precedes even the PC/DOS incarnation
  of MS/DOS and would support multiple users on a 64K 6809 box

- TSC's uniFlex also ran on SWTPc 6809 boxes. Similar capability to OS/9
  but not nearly as flexible or portable as OS/9

- SCO UNIX was also running on 8086 hardware around the same time - 
  multi-user operation on around 128 KB RAM I think

All of these appeared around the same time and all supported simultaneous 
multiple users with 24x80 green screens terminals such as VT100, 
Hazeltine, Beehive, etc. I think Wyse were later but I could be wrong.

Agreed: apart from anything else you'd have problems using more than one 
interactive app at a time on those tiny screens. In fact those early 
smart phones had to have some rudimentary multitasking ability, at least 
equivalent to what the early Macs could do, or the phone couldn't accept 
an incoming call if its owner was using an app.

Palm Pilots were and are extremely useful despite having no multitasking 
ability whatever.
