There are also other problems that need to be solved.

The public hasn't had a chance to become angry about Vista. It's
not been out long enough nor has it been installed on enough

Not at all. OSes were handling the above problems in the 60s.
The reason virtual memory was invented was to solve the above

Your working set is always outdated. You would need to rearrage your
code and data better..espeically the data.

Which obligation am I thereby imposing?

Was it childrearing that addled your brain so much that you
can't understand simple English any more?
