-
- ABSOLUTELY. But "what you use the machine for" becomes, in a very
- large way, a function of the design philosophy of the OS.
-
- One can EASILY see the philosophy that lies behind the Amiga's OS. A
- large part of that philosophy centers around real-time response. It
- has a well-architected and layered design (even if there are some iffy
- parts...). Look at Windows? What was its design purpose? What was
- the point? It's messy, it has no uniform design, it is layered rather
- poorly, and its BASE is very, very poor.
-
- That makes it a bad OS.
-
- What is windows? Is it a real-time OS? Not really. What is it? I
- sure as hell don't know. It's some kind of twisted hybrid, and it
- didn't work.

- Actually, it's nowhere NEAR being like the Mac world, but I'll let you
- get away with that.

-
- Right--Because Windows, just like every other major program for the
- IBM, comes with a huge number of drivers for it. And if you count
- programs that run under windows, considering them "children", it fits
- in with the standard philosophy that exists on IBM systems.

-
- If it does EVERYTHING that DOS does, then it is, period. But it is
- still a VERY POOR OS at that. And that goes back to the above, and
- the architecture of the OS itself.
-
- IF, and I do mean IF, Windows used zero DOS code. I'll still bet my
- ass that's not true.
