RFID technology is nothing new, so a product that senses when a special tag is put on it and launches an application is not a particularly impressive technological accomplishment. It might, however, be an early peek at the future.
Imagine if your computer knew where you put your stuff. In addition to helping those of us who are less organized, it could predict our actions and respond accordingly. For example, if you left with your keys, it could recognize that you were leaving and send a shopping list to your phone or lock the door after you leave (or before you leave if your computer turns evil). Or, as you walk through the room carrying anything that was tagged, it could turn the lights on when you entered and off when you left.
A lot of the technology for this is already here, so how long will it be before our computers keep better track of where our stuff and ourselves are?
