I fully agree, and would never suggest betting your life solely on APRS - after all that's why we carry 406 ELT's in the aircraft and PLB's in the flight bag -
however it is another layer of safety that is easily affordable, and generally reliable, and as such, is worthy of mention for those who aren't aware of it.
