I agree about the 3DS ergonomics. It's just a horrible mess. Glossy texture gets all mushy after a while. 3 different colors/layers, the corners hurt, battery life is horrible, stylus on the back, extendable stylus (why?), buttons back to original DS/lite mushiness as well as small screen and bad CPP.
That's why I never buy a nintendo portable console at launch. I know there will be a new itteration within 1-2 years. I love my DSi, feels so good, as well as the 3DSxl, nice screen, bigger, more comfy, especially with the CPP, and clicky buttons.
Never cared about multitasking or the UI, only the games so I'm not underwhelmed at all. It has the best library between Vita, WiiU, Xone, PS4 by far. I wasn't ever hyped about 3D and like many others I never use it.
I'm a happy camper. Games are all I care, and multiplayer in MonHun works well enough
