I don't think the inventors of the inPulse (or other watches with similar functionality) spent much time thinking about the utility of the device. Is having to look at a small subject line on the cramped display of a watch really better than simply taking out your phone and reading the whole message? I remain unconvinced that the watch will make my life easier in any meaningful way compared to the alternative. It reminds of Nokia's effort at implementing NFC I read about somewhere recently - to buy a soda from an NFC-equipped vending machine, you had to bring the phone in contact with the machine,make a selection, wait for a text message asking for confirmation, and then respond to the message before you got your drink. The designers were convinced that this would be easier than simply putting in a coin and getting your drink.
