No powder, no $$ per scan, scans get sent to the lab instantly (no multiple day processing by 3Shape to clean up the files),models can be built by whomever you want, way faster than what's out right now, easily do lower/upper while holding the scanner in the same position (unlike the rest where you have to reposition yourself, on the Trios you just remove the tip and flip it around),wand is a lot easier to hold also.
