I bought a 32GB version about a month ago along with Super Mario 3D World, ZombiU and a Pro Controller. Zombiu makes great use of the gamepad and is very atmospheric and Mario in HD is just glorious. I bought Wind Waker HD a few nights ago on the eShop and can honestly say it's one of the nicest looking games I've played. I hear great things about Pikman 3 and The Wonderful 101 as well.
That being said, it certainly looks like Nintendo's vision of the Wii U isn't going in the direction they sought. Already we are seeing a lack of 3rd party support. So unless the Wii U starts booming I can't see that changing anytime soon. However, if you like Nintendo made games than I say go for it.
