I'm super happy with my Droid.. I do miss my iPhone 3GS but I have a MIFI that I use while at work and connect my 3GS into it when I want to use it, but overall, my Droid fits me perfectly.
full keyboard, high res screen, iphone like features, apps, and Verizon's crisp call quality.. +++
IMO, the Droid is THE best looking Android phone and probably the best overall user experience in an Android phone.
As a BB admin who has hundreds of BB's with trackballs, they WILL eventually fail. Dirt/sweat is their worst enemy.. and good luck with worrying about warranty exchanges of people's Nexus one.
