Are handheld GPSes becoming a defacto primary nav source?

If I am told cleared to xxx VOR which is say, 200 nm miles away, I am assuming

am cleared to there, so to get there, I will use the navaids available in my

KLVS V190 DHT V234
then expect more at EMP or close to it.
thats how I would take it, unless told otherwise, If I had questions I would
ask.

Jeff, when you're cleared from your present position to a VOR, you're
cleared along the direct course to the VOR, period. You're not cleared to
develop your own route using other navaids or convenient airways of your
choice. That's why you need GPS or other RNAV equipment to fly such a
clearance. [Ref: 91.181 Course to be flown.]
