    That isn't progres. Especially since Linux and Win CE can often not be used for the relevant tasks...

    Linux or Win CE isn't the route to avoid issues with embedded processors becoming obsolete. Lots of hardware needs programs that plays with the lowest levels of hardware. Linux or not, you still have to work with drivers, because stock drivers for a processor seldom supports the full hardware capabilities. Next thing is that Linux isn't an RTOS.

    The only main difference that have happened, is that people use C or C++ instead of assembler, which means that a significant percentage of a program can often be reused. The hw mapping layer may have to be rewritten if switching to a processor in an other family or from another manufacturer.
