Something else. I do not need engine management/monitoring and I do not know of anyone that needs this functionality as a major component of a CarPuter.
Personally, I already have access to this info via my wideband O2 and OBD-II integration, but then this is what I do for a living. This is definitely not a "must have" for most folks.
It's in the "gravy" category - again, IMHO.
