I own a nice ssh client that uses keyboard and function overlays. For quick stuff here and there it works fine. And maybe even for text messages or forum posts a translucent keyboard would be reasonable. But I often edit and stare at code, and I've found my side keyboard terminal program to be the most productive solution at the moment. My opinion is that being really productive on a smart phone is an open frontier, and I'm not convinced we've seen the best solutions yet. And if an apathetic person like myself gave it a try, it's likely others are thinking about it also. Maybe.
