That should basically be treated as the first time that the PalmOS wins on equal hardware. Garmin could have also based this on PPC, but chose the PalmOs instead. Now that is good news!
BTW, I wouldn't want to fly in a WINCE-navigated areoplane. See here for a little dialogue on board:
Pass: What is all this blue stuff here-water?
Pilot:No, thats a bluescreen. And please don't press Strg+Alt+Del, as Alt means altitude here...
Dang, and I thought my NZ90 was pricey. I can see it now if this was PPC based
Co-Pilot: We're going down!
Co-Pilot: The Nav system crashed.
Piolt: Well what are we headed for?
Co-pilot: We're head for water!
Co-Pilot: Blue Screen of Death.
Also, this device really puts the Pilot, it Palm Pilot

I looked at Garmins at the CES show. They seem to be duplicating the IQ series in PPC as well as the Palm 5 units. So there may be a PPC avation unit out soon. They even had a station at the Microsoft exhibit with PPC nav units. They looked very much like the Palm Based ones but ran MS PPC OS.
