Futuristic Mobile Device with Advanced Search Function

The idea behind this concept is exploit the internet ability in a mobile device. Touch screen, built in camera, scanner, WiFi, google map (hopefully google earth), google search, image search all in one slim device. It works like this when you see a building through the device, the device gives you the image search result right on the spot.  Choose a building and touch a floor and it tells you more details of the building. You can use it when you want to know a car model, an insect name, what kind of food is served at a restaurant and how much, who built a bridge, etc. With detail informations like that, this gadget might only be used by secret service agents. Very futuristic concept. 
  
It would be much easier to read a real book. You can use the dictionary, wikipedia, thesaurus and anything else available on the web. What do you think?
