Buy a Switch?  Buy a Wii U?  Buy nothing?

Switch:
+ portable gaming - doesn't need TV or computer.
+ Splatoon 2.  Checks off a box on my wishlist labeled "Splatoon or Splatoon 2."
- $300, and I'm not even sure if that's a bundle that includes Splatoon 2.
- multiplayer requires paid subscription.
- only currently want one game.  I'll consider Metroid Prime 4 but it's not a top priority as far as why I'd get the system.
- not sure any personal data on it is transferable if I get a new system.
+ piss off PC elitists.

Wii U:
+ Splatoon.  Checks off a box on my wishlist labeled "Splatoon or Splatoon 2."
+ Super Mario 3D World.
+ can play Wii games.  I don't have a Wii.
+ free multiplayer.
- $210, for both the system ($180) and Splatoon ($30).
+ if I don't buy it now, it won't be available for much longer.
- requires a TV, I think.  I don't have good access to a TV.  There's a TV here but I might get flak for it if I use it regularly for gaming.
- only currently want two games.  I'll consider Metroid Prime 3 (yes I know it's a Wii game), MarioKart, Smash, and Mario Maker, but they're not top priorities as far as why I'd get the system.
- unpopular system; dunno when Nintendo will stop supporting servers for Splatoon.
- not sure any personal data on it is transferable if I get a new system.
+ piss off PC elitists.

Neither:
+ saves $180 to $300.  (I'm likely to spend $10 or less during the present GOG/Humble Store/Steam sales.)
+ doesn't add to my already-huge backlog of games.
+ doesn't add to physical clutter.
- I'll still be playing TF2 when I want my Splatoon fix.
- doesn't piss off PC elitists.
