It has to have the additional WAAS avionics goodies. Simple GPS needs the

You are picking nits. WASS *IS* GPS, MAN!

You said you could not use GPS alone for IFR. Yes you can, GPS with the
WAAS is STILL GPS!

I really don't want to get into the middle of this discussion, but
what do you think the ratio of installed WAAS nav systems to
enroute/approach GPS/RNAV systems is currently? 1 in 10? 1 in 100? 1
in 1000?

Do you need WAAS to fly a stand-alone GPS approach? Do you need
"conventional" nav gear present to fly a stand-alone GPS/RNAV
approach? For that matter, how does one determine if installed
equipment meets the requirements for a stand-alone GPS/RNAV approach?
