The Motorola DROID Bionic ships with Google Android version 2.2 ("Froyo") pre-loaded, but this operating system is overlaid with Motorola's signature MOTOBLUR user interface.
A version of the Droid, known as the Motorola Milestone, is sold by some international carriers (like Telus in Canada) and it is not equipped with MOTOBLUR.
Just as the Droid Incredible uses HTC Sense, the Droid X has Motorola's unique MOTOBLUR user interface on top of the Android platform.
The Android phone also has the MOTOBLUR interface for "always-on social networking" via Facebook, MySpace, and Twitter.
Motorola CLIQ 2 separates itself from the other T-Mobile cell phones by offering the unique MOTOBLUR user interface.
The Droid Incredible is preloaded with the HTC Sense user interface, whereas the Motorola Droid X has MOTOBLUR 2.
It is also a Google Android phone, but it is overlaid with the unique MOTOBLUR user interface.
Instead of MOTOBLUR, the HTC smartphone uses HTC Sense as its user interface.
