What's the most disappointing game system you've ever owned?

Gamecube. The library was really limited, at least when it comes to games that I personally like. Its the console I've owned that I've used the least.
To a lesser extent the WiiU for the very same reasons. Tho since it was backwards comptaible with the wii I did ended up using it much more than the Gamecube.
