Apple Thoughts: Automate Your Text Messages With Canned

"Lovely new iPhone app that allows you to write text messages before hand, and choose if you always will send it to the same person or not. Either way you can send the message very fast, great tool and it's only $0.99."

Interesting app [affiliate link]. Most of my text messages are conceived on the spot so I don't really see myself using this, but I like the idea of having something like this as an option. I suppose it would work well if I was thinking far ahead enough to plan some messages about travel arrivals, asking about grocery items needed, etc. Come to think of it, I may find a use for this after all. What are your thoughts, canned text messages have a place in your arsenal?
