Apple Thoughts: TextExpander for iPhone/iPod Touch

"TextExpander for the Mac has been one of my favorite utilities for several years. The ability to define "snippets" of text which expand into words, phrases, sentences, or even the outline of entire documents has been invaluable."

This won't run exactly like it does on your Mac, since it can't run in the background, but it can still save you time, which is what the program (and app for that matter) are all about. This app is on sale now in the iTunes store for $1.99 USD until September 9th when the price jumps to $4.99 USD. So you still have time to check out the features to see if it is something you are interested in and still take advantage of the introductory price.
