I certainly sympathize with this concern, given the importance of software
portability. However, the tiny-hardware alternative appears ot some sort
of special-purpose embedded OS, which most definitely will suffer from
software compatibility issues. I guess that the good news is that much
of the tiny hardware that used to be 8 or 16 bits is now 32 bits, which
means that it has at least some chance of running some form of Linux. ;-)
