I got one for the kids because their old Wii was dying anyway. No, there aren't a lot of WiiU-specific games out there, but all of the saves and WiiWare games transferred from their old Wii without a problem. Yeah, it's getting a slow start, but it's still a good unit and it has a lot going for it. I'm sure that exclusives like Bayonetta 2 and Lego City Undercover will help.
The biggest problem that I see is that developers are being stupid. Destructoid had an article a few weeks ago where developers said they were avoiding the WiiU because they didn't know what to do with the gamepad! Well, who cares?! Just because there is a gamepad with a touchscreen doesn't mean that it has to be used! Just as a controller I found it to be very comfortable to hold.
So, come on, developers! Stop being afraid of the gamepad and just make your games for the WiiU! Not making games because you don't know how to utilize the gamepad is like saying that you'll never port to PC because you don't know how to use all of the keys on the keyboard!
