I've had a Droid Eris since December of 2009. I was due for an upgrade from Verizon this August, but I received a text from Verizon last week saying I'm due for an early upgrade. I called the number in the text and the rep said yes, I can get an upgrade anytime from now until August. I really like the form factor of the Eris and the quality of the HTC phones, but of course the Eris is slow and running 2.1. Although I think the Incredible is a great phone, I can't see upgrading to it now that it's almost a year old. Do you fellow Droid users think the Thunderbolt is enough of an advancement over the Incredible to warrant my upgrading now (and being locked in for the next two years), or should I wait for something to come out from HTC that will really knock my socks off from now until August?
