In 2002 when I saw the Spielberg Movie Minority Report, I was impressed with the stuff shown there. John Anderton, the cop played by Tom Cruise entering the chamber of pre-cogs and using that special computer to "browse" through images captured on it. By browse I meant they showed him actually move his hands through a stored collection of pictures, zooming, rotating and resizing them up by stretching and moving his hands.
Of course I don't wish to narrate the story for those who havent seen the movie but they showed this in a future time era of 2050 which after seeing I said to myself.. eh its not that far and I guess we are gonna see computers like that soon.
And recently when Microsoft unveiled Surface... I said wow ! It's really happening. Check out http://www.microsoft.com/surface and with what Microsoft is heading for.. it's sure to rock !
