I also loved my Wii U. It's such a shame it wasn't more popular. I basically used it like a switch with a box that needed to be plugged in, just took the console places and anywhere with an outlet I could plug in and play on the screen. Obviously the switch is the superior console but the Wii U was a banger.
The Wii u was better (when the game developer used it correctly), it was a separate screen that showed different content. It was more like a DS.
Some of the games in Nintendo land were excellent local multiplayer games that will never get replicated again. They made great use of the second screen concepts.
I loved playing hyrule warriors (the first one) on it, because you could play local co-op but not split screen, without needing another unit. It was an absolutely superior experience to split screen.
I wish there was something similar with a higher quality screen, but I think that ship has probably sailed.
I know, I had one, but it also had a base station that was the actual processing unit connected to the TV, so the handheld was essentially a remote monitor. Aka this meme doesn't work because it's missing half the wiiU unit.
Not joking, I'm secretely hoping their new console is the same format as Switch, but lets us use a 2nd unit or an old Switch as a screened controller. Ever since Resident Evil on Dreamcast I've been thinking every console could use a 'HUD in the controller'
