There have been a number of Nintendo mobile device concepts over the years, including some pretty wild design ideas.
But few look as product-ready as this new, Android smartphone-inspired Nintendo handset concept. Created by Germany's Curved Labs, the Nintendo smartphone concept looks like a standard Android phone on the surface.
But hidden in its sides are two traditional Nintendo controllers, giving the device a distinctive look that the company's designers might do well to consider. (It's also reminiscent of the Sony PlayStation Portable, aka PSP.)
To top it all off, a tiny Mario key fob is attached to the device -- the perfect accent for the real thing.
