Usually, whatever software PC's "ship with" is crapware. Go figure.

"Crapware" is just my opinion. Although I've heard others note the same thing.

I think at least some Chromebooks use it. It finds use in HPC clusters and embedded/industrial settings as well.

All Chromebooks except for the ARM model and the CR48 prototype use coreboot.

The ChromeOS developers are currently porting coreboot to ARM, too.
