Hi my idea i am posting here is in the hopes that one day it becomes a reality, i see that Nintendo is making steps into the mobile market which i think is a great business venture but i only why they haven't tried to go into the PC/Mac market with small products such as the one i am about to suggest.
My idea is mainly for people with vision problems, and dizziness such as Vertigo, and other issues. also the common PC player that prefers PC play over other platforms. this would be a plug in device i'd imagine it could possibly stream through 3DS/2DS like a streamstick would (Roku, Chromecast, etc) or it could be just a Plug in usb device but however it's designed the intented purpose would be to be able to play your favorite 3DS/2DS applications, and games through your PC, and/or other monitors, TVs etc. Though i think this would benefit most for PC users. and again this could either be a USB device or a HDMI streamstick type of Device, Roku makes analog TV support packages with their streamsticks for an extra 10-14 dollars.
Money Wise: I see this being something people would purchase often, i think Streamsticks of any kind is money right now. Google just came out with a chromestick for 80 dollars that acts as a Computer to any device with HDMI, it truly is the future and i think it's a door that should be opened by Nintendo as well. Something like this has beneficial use for the customer and economical use for the company going into 2016 and beyond.
