MSP430, with or without OS

[Evgeny Ginzburg]

Hello

I got the impression? that MSP430 have goo chances to be an MPU in 
future hardware design.
I've recently found what open-source OS - COntiki (maybe more than one) 
available for this platform.
 From paper [2] I understand that Contiki have event based kernel, 
sounds good for MPU job and possibility to update/download new programs 
during runtime (there is also possibility to replace the kernel to).

The question: Is it possible or desirable to have a such "full" OS on MPU?

P.S . I'm a nonprogrammer so _can_ speak absolutely nonsense.
