Have you ever heard about MessagEase, the extremely fast and efficient text-entry method for small devices? Probably not, even though it’s been around for a long time. And why not? I firmly believe that it’s because of the learning curve — it takes at least a few hours of practice to see any real speed improvement over whatever method you’re using now.
It’s ridiculous, because if you enter any significant amount of text in a device, MessagEase will save you lots of time in the long run. But most people would apparently prefer to limp along on what they already know than invest a little time in learning something that’s superior in every way.
Once the iPhone version of it becomes available (it’s supposed to go into beta before the end of this month), I’m sure more people will be exposed to it. We’ll have to see how many of them adopt it.
