I had an Eris as well...only got about a year out of it - moved to DroidX, but didnt like it - too big, too hot. So I got Fascinate - which I love. Awesome Screen - the "Bing" thing is not a big deal. its a great phone.
in all reality, Droid Incredible, DroidX, Fascinate, Droid 2 - you can't really go wrong - all will be a MAJOR upgrade from the Eris.
