>Or is the definition of desktop computer that it can, say, run Adobe Photoshop natively?
My point is that the Chromebook is a mobile device: it's tiny and easy to carry around. So why is it not in the "mobility" category? And for that matter, why is every laptop computer not in this category? When did "mobile" somehow become equal to "something you can carry in one hand while also operating it"? The entire point of laptops was that they're mobile. These days, not that many people use "desktop PCs", outside of corporate offices, they use "mobile devices" (i.e. laptops).
And where do tablets fall? You can prop them up on a desk and attach a keyboard, and they act just like a laptop (you can also connect external screens etc.).
As I said before, their categories are stupid.
