Those are the big ones, for sure.

Hijack adds a few good ones that I like:

- Monitor internal unit temperature from the main screen.
- Audio dynamic range compression.
- Force the boot-up volume to be at a predetermined (low) level.
- Left/Right listening position adjustment (time delay alignment)
- Infrared code translation

Each of those could theoretically, with a certain amount of work, be implemented in a PC.
