Nonsense. Surely you jest.
Nearly all STB hardware has C/C++ hardware device drivers. For I/O and
other functionality, what isn't available in standard libraries is
widely available in cross-platform libraries. Its easy to extend
middleware C/C++ in the upward direction with something like Boost, and
its easy to extend it generically across hardware using uClibc and
others. It is not uncommon for these libraries to support a dozen OS
platforms and a dozen hardware platforms at a crack. And direct
interfacing to the system level/kernel is much easier.
So really, your argument is the much-quoted party line that only
impresses the ignorant.

Nonsense. The Java VM runs on top of OS's built on C/ASM/C++ code.
As for security, my previous employer was in the business of smartcards.
Java had no place there. Let alone the fact that Tom Dick and Harry
aren't going to be running their 'rogue C' applications on a STB -- it
is in 99% of cases a flash ROM.
Embrace the pointer, Bill! :)
