I think it's a great step in the right direction. I would love to just play with a laser keyboard. But probably wouldnt switch to one right away until they are suitable for fast typing and gaming.
Just think, if you had a laser keyboard (well an evolution of one), you would never have to buy a different keyboard again. (Well unless the one you had broke). You could basically switch the key settings, adjust the keyboard to fit your own style. No more buying the "ultimate gaming keyboard!", just adjust your laser key settings and you have your ultimate gaming board right there with little hassle.
Blah. you get what I mean. Great stuff. I like where it's heading. Wont be long till we wont need Computer Monitors anymore. Maybe they will find a way to hologram the projection instead of needing a big screen.
