Had one about a month now, got a basic for 99 squid in the recent tesco clear out and stuck a 64GB stick in the back.
The games ive played Ive enjoyed, Nintendoland, Bayonetta 2 (wow!), Smash Bros., Super Mario.
I do find the interface quite dated, especially the eshop. The normal controller is clunky and the screen on it is unresponsive compared to my smartphone or vita.
I like that its back comptable with Wii games though.
