Last time I was in a paper-factory I was more than happy (and dripping in sweat) when I could leave the production hall after less than 1 hour. Here you really really want to have your controls in a sepearate room. You also want big screens to (easier) keep track of all your data.
Tablets/Laptops might be a good idea for the manager wanting to keep track of production numbers or the mechanic checking/repairing one smaller machine of the factory but are a nogo for those you have to keep both eyes on the whole thing.
Desktop will also stay pretty dominant for most creative work (sure photoshop runs on laptops,but runs better on a desktop) and the usual office stuff (laptops simple aren't ergonomic when typing 8h/day).
In the private sector where people these days mostly seem the visit facebook&youtube desktop is allready pretty much dead.
