I have to say, after my initial backlash against the Switch, which lead me to cancel my pre-order, I've been loving it.
I've bought a ton of content from the Nintendo Store all for less than the cost of a PS4 game - Shovel Knight, Fast RMX, couple of Neo Geo games and Graceful Explosion Machine (ok, maybe a little more than 1 game) - and am getting exactly the experience I want from it - Compelling handheld gaming on the sofa and on the move. The battery canes on fast RMX but it's genuinely good to excellent on the less demanding titles. I reckon I'm averaging 6 hours gameplay a charge, which is about what I get on my 3DS.
Have pre-ordered MK8 as I never got around to all the DLC on the Wii U and that will take us nicely into the summer when Splatoon 2 is out.
