You are basically correct in your analysis of the new Direct Connect on Sprint; however, the difference between the new DC phones and say, the Moto Renegade is the 800 mhz frequency with the future roaming over PTT capabilities. I do not think that any of the old QChat phones will ever be able to roam on PTT calling.

There was also a battery consumption issue before. The technology and chipsets in these newer DC phones have W A Y longer battery life. When I carried my Renegade, it wouldn't even last an entire day without going dead--even if I barely used it. I eventually had to buy an extended battery (and door) for it, which made the phone look and feel bulkier.

I never had any software issues with mine, but others apparently did. I just couldn't keep the thing away from a charger long enough to use it.
