Besides it being pretty fugly it look like its more comfortable and it fixes complaints. People bitched about the analog sticks being too close. Now they're father apart. They complained about the shoulder buttons being too small at least the ZL and ZR buttons. Now they're bigger and seperate. People complained about the size. Its bigger now and while it looks ugly it looks like it might be comfortable.
Like the DSi people love to bitch and moan about more options.
