The Wii U GamePad is a controller used by Nintendo's Wii U video game console. Incorporating traits from tablet devices, the GamePad incorporates both traditional input methods (such as buttons, dual analog sticks, and a D-pad) and a touchscreen. The touchscreen can be used to supplement a game by providing alternate, second screen functionality or an asymmetric view of a scenario in a game. The screen can also be used to play a game strictly on the GamePad screen, without the use of a television display at all. Conversely, non-gaming functions can be assigned to it as well, such as the ability to use it as a television remote.

The VMU, or Visual Memory Unit is a memory card peripheral for the Dreamcast
While its most basic function is as a removable storage device, the VMU may also serve as an auxiliary display during normal gameplay and, through use of additional software, act as a handheld game console. Console-like features of the VMU include a small black and white screen, speaker, directional pad, four buttons and the ability to download additional games. Initially only available in white, colors were expanded to transparent Red, Blue, Green, Yellow, Black and many other color variations.

So which do you think was the better innovation?

Hmm, both are pretty Jizz worthy but I will pick my sex toy instead

The WiiU GamePad wins thanks to porn!

i dont see the VMU as an innovation. it was a tamagotchi build in a memorycard...

Oh come on, tablet porn existed well before the Wii U came along =P

It doesn't matter! In this case the GamePad is still the winner!

I haven't seen any wii u with multiple gamepads, retarded to only have one when multiplaying

I think the VMU is very, very nice. It's the small things that make something awesome, you know? I don't think it is comparable to the gamepad though.

Its not even comparable. The gamepad has uses, the VMU was completely useless and didnt have much memory to boot. So, even as a memory card it failed.

gamepad.... not even really comparable honestly.
