Sorry to be pedantic, but I think there is a mistake here. Multitask refers to parallelism capability, on the device (HW/SW) side. It is not necessarily associated to multiwindow.
For example, iTunes can run several tasks in parallel. These tasks have of course been launched by the user, but not at the same time (although they execute in parallel), and without a need for separate windows displayed at once.
« Multithread » is the right expression to designate parallelism on the user input side (= i.e. within the user's brain, not within the computer).
Indeed, although we are inherently limited by human body design (we only have two hands , etc …) , a user may run several courses of actions at the same time (e g talk on the Phone and drive his car (although it is forbidden in most countries).
The degree of such multithread capabilities may vary, according to the intellectual capabilities of the user, as well as his degree of training (most extreme case being probably the fighter pilots).
Such multithread capabilities increase mental workload/stress, and, apart from exceptional cases (yes, a fighter pilot must at the same time run its plane, check whether he is attacked, and possibly attack) cannot be justified in normal cases, since the popular wisdom says that if you try to do too many things at once, you just fail at all ...
In the example you mention, there is multitask (all monitors are refreshed in parallel), but no true multithread (the user does not interact within all these windows at once). Without this capability, you cannot claim multitask alone increases his productivity. His productivity depends on his agility to focus from one window to another (the fact that they are displayed in parallel being a necessary, but not sufficient condition for this).
If your point was to advocate for multi window capability only on a portable device, it is weakened by the fact that you use an example where you do not just have multiple windows, but multiple monitors, which is different ....
