It's a combination of sensors and emitters for various commonly used protocols and frequencies all wrapped up in a nice little package with a microcontroller that can run custom code ('apps'). A lot of people buy it hoping to be the next l33t hax0r but its not a mainstream gadget. I got one in the first post-kickstarter shipment and its a pretty slick device with a very steep learning curve. I mostly use mine for 2 things. 1: To keep a copy of all of my key cards for my various clients (I'm a consultant) and 2: to turn off annoying TVs in public places.
