If you are a heavy smartphone user, particularly if you happen to fall into the age gap between too young to think voice control and answering machine messages are super awesome future things and too old to have grown up with video messages, there is no "just a keyboard". You'll be so adapted to the particular behavior of your chosen smartphone keyboard that changing would be like an involuntary migration to dvorak. Or perhaps even worse, because there's so much more to interactive touchscreen keyboard behavior than just layout.
