I bought a Droid last November and have gotten used to the arrangement of keys...work forced me to Verizon, probably good since AT&T has such a bad reputation as a carrier.
Google can't even make up it's mind either...I think the way that my original Droid is set-up works great, but I'm sure there are differing opinions out there.
In maintaining the tradition that "mobile phones should frustrate people..." Here is an Android collection.
Which one do you like best? Droid? iPhone 4...
