I don't know... if focusing solely on hygiene, touch screens easily have the upper hand (at least potentially, if people cared about ~disinfecting them in the first place) over keyboards and mouses.
And I can easily imagine touch screens turning out great for many kinds of serious work (~CAD for example - we definitely lost something when moving away from drawing boards, and touch UI can build upon their model in ways that desktop OS & mouse cannot; also, film or graphics editing)
WRT dust ...well, that's a separate issue, touch screens or not - but the related gradual move towards "good enough" chips, without active cooling requirement, also largely solves it.
I can imagine touch screens having specialized uses and CAD could make sense on appropriate hardware but this is MS office word-processing, spreed sheets etc. This just feels like something being hyped up to separate fools from their money with very limited usefulness in general computing.
All that reaching over the keyboard to touch the screen also looks like a recipe for backache.

Ouch!
Seriously do you think a touch screen, used everyday in an office or a heavily used laptop is going to be a pleasure to use. I've seen the touch screens in the computer retailers and I fear to touch them.
Touch screen might be good for a phone or one of those iToys but for work - no!
