I am finding it useful when I get caught in long lines at the store. I have loaded the Kindle app and so always have a book with me to read - that's a good thing. Also on the upside, my frustration with the dominant text and function entry systems that Janus seems to share with a variety of touchscreen devices has led to a software concept that I will explore with some entrepreneurial friends. Which leads to the 21st century daydream of being wealthy enough to turn your back on digital demands. Think about it: "Jeeves, take an email," or "Jeeves, bring me the New York Times crossword on the terrace with pencils, and freshen my orange juice," or "No, I really don't care what searches are trending up on Google."
On the confusion side - where are you supposed to put the thing? I suspect that Janus makes his surreptitious calls when I put him in my shirt pocket. Putting it in a pants pocket creates bumps and bruises on your thigh. If you don't carry a purse or backpack you are reduced to carrying it in your hand, which, of course, inclines you to use it, to put it on the table, to make it your new BFF. I suppose one can get a belt clip - but that makes me feel vaguely like a meter reader with no particular meter to read . . . .
