> On a more constructive note, MS-DOS and Windows operate on a fundamentally different philosophy from UNIX
Not sure I follow. There are many concepts in DOS that are the same as Unix: pipes, redirecting output, stdout, stdin, and stderr. DOS's batch language was limited, but conceptually it allowed for very Unix like chaining of commands. I suppose you could argue / vs - for command line paramaters... but conceptually they were similar. Unix file systems could be case sensitive or not.
I think about the only thing that philosophically was all that different was drive letters, multitasking and multiuser. Unix didn't do drive letters, and DOS didn't do multitasking and multiuser. Eventually Windows did, and grew up to compete nicely with Unix.
Why would anyone who can run DOS run Linux?
On a more constructive note, MS-DOS and Windows operate on a fundamentally different philosophy from UNIX. That doesn't make them inherently bad. The vast majority of users even relate better (FSVO better) to the way Windows does it.
