I'm with Glaucus on the laptop/desktop issue - a laptop with peripherals plugged is is definitely still a laptop, because it can be moved around and used standalone without the peripherals - the same cannot be said for a real desktop i.e. a PC case that has no input devices, no screen etc.
In fact in the corporate market that is kinda the whole point; many employees need laptops for remote working but you don't want to have to give them a desktop as well for office work so you provide them with peripherals to use when in the office. Even within the office, a laptop is different from desktop as you can easily take it into meetings etc, something that can't be said said for desktops.
Describing a laptop as a desktop because it can be plugged in and used at a desk is a bit like describing a car as an apartment because you can sleep, eat, listen to music in it etc. Bad analogy because you don't plug much into a car for the above other than CDs, food and maybe a pillow, but I could probably come up with something better if desired.
