For the more adventurous crowd, there's another keyboard option that ships disabled on the Droid X by default: Swype.
Swype itself is a different and groundbreaking way of inputting text. Instead of tapping to mimic a keypress, Swype works based on continual smooth swipes across the keyboard, with sharp changes in direction and a few other gestures denoting the characters that create a given word. You don't input the entire word character by character; you swipe over the characters that form the word. Swype does some math behind the scenes, decides what word you likely meant, and pops out a word.
It's mindbending to run your finger across the keyboard instead of tapping. It's even more of a twist because you might have to relearn the QWERTY layout a bit -- I felt overwhelmed with the first few words I tried. After a few days of practice, I was screaming along. The only side effect is that typing on a normal keyboard now feels odd; the first time I went back to my keyboard I found myself wanting to Swype.
