> Minority Report should've featured Tom Cruise with gigantic arms, built up from years of holding his arms out in front of him all day just to do basic computing tasks.

Gigantic arms like you get from holding your smartphone the whole day and using it? I would guess that it might be even better to work this way than sitting 8 hours in a chair using the keyboard of your computer or your smartphone.

Sure holding your arms out to type on a 'virtual' keyboard probably wouldn't give you gigantic arms, but most people would find waving your arms around to interface with holograms in the air tiring if they were doing it for 8 hours. I don't wave my arms around in the air when using a smartphone most of the time. :P

Also, there are downsides to standing all day, just as there are to sitting.
