Can I borrow your phone for the evening? If you want you can pick it up when you see me on Monday.I'll admit, maybe I'm only looking at this from my own POV. I have two Switch consoles, a pretty decent Android tablet, and also a Nvidia Shield TV. I guess if someone only had just the Switch device, they might want access to all the other things that Android provide. Where as I have a Android tablet and a Android phone. Having the Switch run Android would just turn it into another Android tablet. From my POV, there's nothing cool or exciting about that.
Now replace phone with (hacked) Switch.
Less obtusely it has the makings of a great temporary/lendable device. This in addition to the things I was on about earlier with the ability to chain things together that correspond to my very specific and unlikely to be widely shared whims, and it being unlikely that there are many develops champing at the bit to start making things for the switch (practically speaking it is another android device as far as power and features go, with the added bonus that I can't sell my code very easily and probably also have to do the hack-counter hack-hack routine that locked down device developers go in for in the modern world).
