Pre-emptive Single Task Operating System++

A while ago I wrote a blog entry about a pre-emptive single task operating system that I think the world needs. It seems I'm not the only one and George RR Martin (Game of Thrones) also thinks there's a need for this. His seems to stem from security as well as a productivity perspective but I think I grok what he means. The feature bloat in products such as MS Office these days detracts from their usability. They may be able to boil the ocean but it's not really necessary and just gets in the way of the creative process. However, DOS surely has a limited life and it must be hard to find the h/w components to run this on now. I may fire up a VM with DOS sometime to remind myself of the good-old-days... need-for-a-preemptive-os++
