Although the aesthetic design of the Wii U controller may look similar to tablet devices, Nintendo of America president Reggie Fils-Aime points out that the company is not trying to tap into the tablet market.
During a VentureBeat interview, Fils-Aime spoke about Wii U's development and how it took place before tablet devices gained the popularity we see today:
We were well in development before the the birth of tablets and, again, to be clear, this is not a tablet. It is a connected experience to the base console. It talks with the base console. It interacts with other Wii accessories whether that is a Wii Remote Plus or a Wii Balance Board. So it has very different functionality compared to a tablet.
When asked about the functionality of the controller and how close the hardware that was shown at E3 was to the final product, Fils-Aime replied:
... we believe [the controller] is going to satisfy the needs of all kinds of consumers that will allow for new experiences and yet still will be affordable and be consistent with the value philosophy of Nintendo... In terms of the form factor of the console, it is quite near final. Similarly the form factor of the controller is quite near final.
From the images you have seen of the Wii U console and controller, is there anything that you would like to see revised or changed?
