The user interface on the Droid Pro and Droid 2 Global differs ever so slightly. The Droid Pro features a full portrait QWERTY keyboard underneath the 3.1 inch display. The keyboard itself is slanted ever so slightly to help with one handed typing and the spacing between keys is decent, though not the best. The overall keyboard experience on the Droid Pro is decent, though if you have larger hands it may start to get harder to type.
The Droid 2 Global, on the other hand, has a slide out landscape keyboard, which makes the keyboard larger and spacier than on the Droid Pro. The keys feel nice on the fingers and they are highly responsive. Typing on the Droid 2 Global feels natural and even users with larger hands will not have much of a problem using the keyboard.
Regarding the touchscreen itself, both have responsive touchscreens and the user interface between the two is extremely similar. They both offer options such as IP VPN for the business user and the Microsoft Office product integration is decent. Using either smartphone for work on a Word document or Excel spreadsheet feels fairly natural.
Overall, in the user interface arena of the Droid Pro vs. Droid 2 Global battle, the keyboard is the make or break deal, and the larger, landscape keyboard of the Droid 2 Global puts it above the Droid Pro.
Winner - Motorola Droid 2 Global
