You haven't seen much. I've programmed in Win95. Sure there's some DOS
legacy stuff in Win95 still, but none of DOS's memory limitations. And
when they talk about 32-bit code, it means function pointers (code) is
32-bit, not DOS's 16-bit... Win95 code is downwardly compatible with DOS
code, but DOS is not upwardly compatible.

What's true multitasking? I think threaded preemptive (but not interrupt
driven which Win95 uses) qualifies it quite well.
