And not just driving. Take the iPad, for instance - it's fun and kind of magical, but a lot of us dismiss it because you can't really do "serious" input on it. Even though I really like it, I have to confess that I can't really type that fast, nor is typing comfortable enough to do for very long. But if typing on my iPad were as easy as it is on a chiclet-type keyboard - just a step or two down from my laptop keyboard - then suddenly things would equalize a bit. And what is for many people the major barrier to using a touch device exclusively would disappear.
