You know, that iPhone of yours has been a revelation. You really have been posting a lot more!

Would you say that apart from the fact that it keeps you occupied on the bus, that the fact that there's only screen space for the app helps you concentrate? I think with computers these days, it's so easy to distract yourself because it's so easy to go from one thing to another. My theory is with the psychology of the smart phone, your app takes up the whole screen and your attention and swapping between apps takes a little more effort.
