I am truly amazed by the intense attention to detail that I see with this console. It is all the little touches that really stand out to me.
The rounded edges on the disc make me wonder why no one has done this before. It just feels right. The animation for the Wii -> WiiU transfer is amazing The TV remote abilities of the Gamepad is a wonderful touch The curtains on the browser. Even including a way to give the webpage a drumroll to introduce it
None of these things are necessary, but all of them are great touches that make the experience a little better.
Everything I see in the console suggests that they really care about it.
