Hell, this is the best sign yet that the switch will have SOME value beyond "you can play the latest Mario here"
Multipurpose portable utility computing platforms are all well and good, but in a general sense are a jack of all trades and master of none.
I prefer to read on a kindle. I prefer to type on a laptop. I prefer to watch movies on an iPad. I carry my DS in case I want to game. I also carry a DSLR in case I feel like taking photos.
I can guarantee I get more work done on my laptop on the train than the guy with his iPad, and I take better photos than the guy with his phone out. I like to think I enjoy the gaming I do on the train more than the people playing bejewelled to pass time.
I've not weighed my bag, but it usually contains:
* 6D DSLR body, 20mm f/1.4, 35mm f/1.4 85mm f/1.4. (About 4KG total of lens & camera.)
* Xiaomi Notebook Air 13" (About 1.2 KG.)
* iPad Pro 9.7.
* Kobo H2O.
* Nintendo DS.
And other sundries: A couple moleskines and pens, a leatherman, headphones, a 20k mAh USB battery pack and lightning cable.
That said, it's easy to see why Nintendo's focusing on gaming: it's their core competency, nobody else in the tablet space does serious non-casual gaming well, and it would be a tremendous undertaking to make the Switch into a real iPad competitor.
