My Verizon experience today:
SoHo - NYC - Corporate VZ Store
Very nice guy, very honest, had a Moto Droid so he seemed to know what he was talking about.
Bullet points:
I asked him about the update to 2.1, and he said, "We where originally told April, but then it got pushed back." I then asked him if it was because of the Incredible. He replied, "No, I don't think so. They said they where still working out a few bugs."
He also even said that he got to play with the Incredible for a little bit, because they had models for training. So, he was being pretty honest with me. Very good experience, as I always have with Verizon.
The last thing I asked him was would the Incredible replace the Eris? He said, "Absolutely not, we still plan on carrying accessories and supporting the device fully." So, I also don't think they are going to hang us out to dry.
