I do think it led to the switch concept which has been very successful for Nintendo, my friend who had a wii U thought it was great, but just wanted the tablet to have better battery life.

They actually sold a bigger battery at the time. Can't find much mention of it anywhere now, but Wikipedia lists it: https://en.wikipedia.org/wiki/Wii_U_GamePad

> LiPo 3.6 V DC 2550 mAh (upgrade WUP-013; 8 hours use)

Agreed, the Wii U tablet controller was a proof of concept for the same form factor that would become the extremely successful Switch.
