I can't agree with what he says about Nintendo making industry standard interfaces. I strongly dislike most of Nintendo's user interfaces.
The 3DS Interface needs work. The folders need real icons, as all mine have a massive "G" on them, for GBA, GBC, GameBoy etc. It's ridiculous. This isn't industry standard at all. I also didn't enjoy using the Wii's interface, switching between SD and internal channels.
Also, how the VC game channel icons would flash between the game title and the system the game was released on is ridiculous. I could never find what game I was looking for because it kept displaying the system it was released for, rather than what game it actually was.
They should also fix the long times when pressing the Home button on the 3DS and Wii U. And how this button becomes disabled at times when online or in the eShop. Xbox 360, PS3 and Vita do not have these issues. The load time isn't long, but the other systems act instantly. Nintendo needs to address this.
