I guess so. Actually I would think more of using an OS where I thought the future code might need to grow new functions, and the speed/memory hit was not a problem. It does provide a framework for adding functions without very little rehash of the underlying framework.

But the memory hit on a '51/52 is quite hard. I would modify the one I was using to allocate stack size seperately per task if I was going to use it seriously. It's really better suited to platforms with more memory.

Doing it was a great way to learn about that though.
