How would have been the computer world if Amiga and Atari would have survived?

Most people would still remember what it meant to crash a computer.

Amiga Inc would be producing creepy snowmen for Atari based mobile phones (which would be the size of toasters and not be able to dial and look at your phone book at the same time).

I think what doomed the Amiga was the mounting of the Graphics chips on the motherboard and trying to develop them in house.  They didn't have the R&D to continue the OS, what gave them the idea that they could do the graphics as well?

In the end I guess there must be an alternate universe where Amiga and Atari survived and Apple and Microsoft didn't, but it probably self destructed shortly afterwards....

Modern OSs do a lot that '80s OSs didn't, I doubt a modern AmigaDos would be any smaller or faster than OS X, MS Windows or Linux.
