Laptops came on strong in the mid 1980s!!
NOBODY will do anything useful for hours on a stupid tablet or even a laptop (unless forced to by economics, etc).
Mobile will die before desktops do.
Its common sense.
We are in the process of getting rid of all our laptops for our field techs with tablets (around 200-300), they're smaller, and way more mobile that the old toughbooks they had in their trucks.
