My friends don't pay for individual texts, but I see your point. (Even though an app like this would likely have to use SMS in the background anyway. And if you're friends aren't hip enough to have an SMS plan, what are the odds they are all going to have smartphones and this little app running? Approaching nil.)
I do take issue with the slow and inconvenient part. It's real time and much less distracting than a phone call. If you stick with it for a few days you can type messages at a surprising rate and it really is faster than a phone call. You don't stop what someone's doing and take over when you send someone a text message. SMS has the convenience of email and the immediacy of a phone call.
