Ah, the joy of abstract statements with no supporting data! The revelry, the excitement!
Supporting data? Do you think fat is a good file system? Maybe you could supply some supporting data to that statement.
No, but the downside is that Linux lacks the same amount of standardization. What would Linux do if Linus died suddenly?
Do you really think the os linux is entirely reliant on linus torvalds? Don't be ridiculous.
Linux isn't limited by legacy dos, of course, silly. It's limited by conventions of *nix, because it is based on it, and if you changed it too much people would say it wasn't linux.
What are these "conventions of *nix" that linux is limited by - explain please.
I suppose you *could* set up an OS which uses two processors, each handling a different program, neither program interacting with each other. (Add RAID arrays... hmm...) Hence, you are running two tasks at once. The word 'Multi-tasking' makes sense in that context, if freed from encumbering connotations from early computers. Who says they both must be working on the same program? They *can*, but could be made to work independently as well. Each processor is not multitasking, but as a unit, the computer and OS are multitasking...
Or you *could* use solaris/aix/hp-ux - the word "Multi-tasking" makes sense in that context.
