At the Taiwan Broadband show Ericsson showed off it’s take on a portable computer of the future. It uses a pico-projected screen and laser-projected keyboard. At least you won’t make any noise while typing. Pictured above is just the prototype.
Ultimately they would like to house it in a spider-leg tripod design. It would have wireless broadband connectivity and of course a battery. Laser projected keyboards by 2020? We can do better than that by 2020 can’t we? I think so.
