Did Microsoft just uncover RT’s killer app? Not the typical App Store app. A combination of hardware and software – can’t use firmware, as that term already has implications, - perhaps we can go with Bladeware. Blades could end up being the coolest new addition to Surface | CITEworld If I’m interpreting it correctly there are numerous sensors below the touchpad surface that put the whole expanse up for grabs. Is it just a matter of a printed overlay and a custom calibrated app? It might make custom blades extremely affordable. Say something like this to simplify CAD input for piping, complex masonry/tile work. Or this to allow patient monitoring without interfering the current image on screen. Seems like a lot of possibilities for field work.
