"desktop" is a totally useless and nonsensical classification, when they do not (which is obvious from their numbers) count laptops plugged into a screen & keyboard for the duration of a workday as a "desktop".
Laptops/desktop are a form factor / product category, not a usage pattern.
The same way as 20kg desktop PC on boats are not "laptops".
Sometimes you do need to know how its used (e.g. if you sell peripherals that only make sense for "road warriors" you will want to know how many use their machines at a specific location all day, regardless of form factor), but most of the time, laptop/desktop distinction based on form, like the one we always been using, makes far more sense.
