So I'm having a tough time choosing what game to buy. They both come out on the same day as everyone knows and I can only buy one when they drop since I need to save some money for a trip in late December. So I wanted you guys opinion on which one I should buy Pokemon or Smash? I want Pokemon since it's pretty much my top Nintendo series other than Mario Kart. But Smash is also special to me and I want to be there with everyone when it drops. Thanks in advance. 

I always bring it to work since I work at a gas station and I work slow nights and sometimes overnights. A lot of the time in the overnight shift there are no customers for hours so I just plug mine in and play on the Gamepad since the TV at the station shows the cameras. I play for hours and it really helps pass the time.

I was wondering if anyone uses their Wii U as a portable system and what places do you bring it to?

I'm wondering how long will the Gamepad last? Like the streaming tech behind it. How long does whatever it uses to stream the game to it last, 5 years, 10 years? This interests me because I don't think something like that would last very long and then eventually over time the Wii U would turn into a standard system like past ones where you can only use the Pro Controller and not the Gamepad.
