They should start with a much more than capable entertainment box that can be expanded upon with software and wireless hardware (inclding, but not limited to this QoL stuff), adding streaming channels to take on things like Roku and Chromecast, actually use it's built-in features to it's advantage, like system wide videochat, real multi-tasking with the gamepad (i.e. doing something other than what is on the main screen, Like netflix on TV, whiie internet or VC game is on gamepad).
I don't know what Iwata has planned for Quality of Life stuff, but it would help if they helped realize the potential of their current business venture before they start expanding into other business arena's.
and considering they seem to already be resource starved for gaming, I can only imagine how many less games we will now be receiving now that Nintendo has hit's attention split.
