The original DROID blew everyone away. It saved Motorola from almost certain bankruptcy, breathed new life into Verizon's smartphone catalog, and made Android a desirable mobile operating system rather than a cheap alternative to iOS. In short, it ushered in a new age of Android devices.
A lot had changed by the time its successor, the DROID 2, launched. The latest Android handsets had larger displays, better designs, and (perhaps most importantly) less buggy custom UIs.
