We had a microsoft partener bring one of these to a talk last week.
Got to have quite a good play with it. It works very well, i wasnt expecting it to be anywhere near as good as it was.
Its essentially a medium spec desktop running vista, there is then a shell over the top which prohibits general user access to the OS - they only get at what the owner wants.
touch panle is incredible, it can detect about 90 simultaneous touches at the moment (uses 5 IR cameras pointed up from underneath to detec and track the touch. you can tag items with binary logos, which the camera can then log and store as a recocnised item.
Think i should poijnt out that this is primarily a Point Of Sale console, more than a home user table.
They've benn installed all over the world in varios bars and restraunt, there are some in a las vegas casino etc etc
They've already started putting them out in this country - barclays bank have got some for use (think its currently only in the new branch in central london- forget exactly where!)
But they've also trialed them in the AV retail market, makes it very easy for a salesman to present information and explain packages/different setups. MS are claiming it incresed closure rates by 50%
May be seeing more than you think over the next few years.
