Paul,
 
1.  As today, some of your traffic is not WAAS located, but deduced by radar and xpdr.
 
2. TIS-B replies (transmissions) are tailored to the puck surrounding the ADS-B Out aircraft. Thus, TIS-B traffic will not be true if you are near the edge of the other guy's puck and someone is bearing down on you that is located outside his/her/its puck.
 
3. You are not contributing to the accuracy of the traffic resolution system if you are not transmitting your WAAS position, vector and trends.  Thus, the other guys/gals/them in the puck are getting your inaccurate position information.
 
4. That's OK, buy the cheap partial solution today - you'll still need to get the full boat by 2020.
 
5. Remember that if everyone is getting weather in the cockpit, the traffic around a storm could get a bit denser than you might be comfortable with.
 
6. Also, if everyone is thinking like you the system won't improve until 2020.  Someone has to be sending ADS-B Out.
 
There is some new neat Garmin stuff
go look at
 
 
and
 
 
Compare and Contrast................ think about how you would prefer the info to be displayed.  The Garmin 88 seems to be pretty intelligent.

If I have ads-b in only and my traffic is waas positioned, then why is this not accurate?  If I don't broadcast then the other traffic may not see me in non-radar areas but I don't see how that decreases the accuracy of my own traffic info on my ship.  Please explain.
