Does anybody want touchscreen monitors? It just seems like 3D -- a pointless feature pile-on from commodity electronics firms desperate to dodge the grinding down of previously high margins.
I keep poking at my wife's rMBP[1] screen. Not all the time, but certain UI affordances mirror their iOS counterparts sufficiently that despite 30 years of not poking at screens, I find myself poking at them unthinkingly. So yes, I think whether we actively "want" them or not, touchable screens likely serve a built-in instinct and as such, are inevitable.
1. Note: I never poke at my own non-retina MBP screen, but do poke at her retina MBP. I wonder if this is because my iPad and iPhone are retina displays with touch screen, such that UI elements are both touchable and without visible pixels, crossing the "uncanny valley" into being "real" interfaces instead of metaphors, causing similar elements on the rMBP to instinctively feel equally "real".
With a production of 250 units/month, I doubt I'll be able to get one any time soon. That's assuming I could even afford what is likely to be an insanely high price.
