Lol. Not even close. How many 20-40 year olds do you see walking around with this thing? Kids sure. Hardcore? This is well off the mark.
The Switch is perfect for me and i'm in that age range. I can take the portable with me to work, keep it in my locker and play it during breaks and lunches.
Take it home, plug it in and continue on the TV.
How is this really any different than carrying around a Gameboy, or a 3DS, a Vita or even gasp a Smartphone or Tablet?
I can see not using the controllers for multiplayer because they are small. But they don't look very awkward. You can't knock it until you've held it. It might just *work*
There's also the possibility you can still use other wireless controllers instead of those as well if you choose so.
And when using them standalone or with the tablet. They look great.
Stick placement on the Wii U Gamepad and Pro controller was awkward for me personally, to use to try and reach any of the face buttons. It was really uncomfortable. Not horrible, but I greatly prefer the face buttons up top.
