I think that the belief that the common individ. isn't interested in multitasking is the biggest load of hooey in the world.
Show me one teenager ...throughout the ages...who wasn't listening to music, watching tv, playing a game (of some kind), talking to their friends (and / or texting) , surfing the web (nowadays) and doing their homework all at the same time....

And that is just teens...

I'm no teen .. but I know that I tend to have more than one process, program or application running at the same time..
reading a book and listening to music...etc.

This belief that no one wants multitasking is beyond buffoonery ...
It isn't that people don't want multitasking...or they aren't screaming for it...
They populace are expecting multitasking as a "de facto" (or matter of fact)...they don't have to voice it...it is an expectation from the technology...

Just wait for the 1st review of it running...
doing something on device ...then ...what the hell...incoming call...message...email...whatever...I'm guessing that answering that call (or whatever) while doing something else constitutes multitasking...so said program shuts down ...to answer the call...
and that to me...that sucks..big giant testicles ..

I've been doing some reading for a bit on the new Ubuntu phone...
and what it "can" do in multitasking results in heating up stupidly ...and draining the battery ridiculously ...(even while in sleep mode) after such usage..

I would love a device which is part of an iot ..so my laptop could run the same as what is on my phone or tv...or sync everything together..but ubuntu phone isn't ready just yet...
I think they're close ...but not quite yet.
