1. Useful gimmick =/= useless gimmick. I don't like Joy-Cons but I cant deny that they are useful for a lot of innovative uses. WiiU gamepad was an old-fashioned tablet, heavy, bulky and often used in bad ways (aka replicate main screens, destroying battery life)
2. Switch is not a bad name because it allows to identify the console immediately (no confusing parents at stores deciding between Wii or WiiU) and it symbolize a change of pace for Nintendo.
3. Playing BC is acceptable only if doesn't require other investment for accessories, especially if they are priced. Better not having at all. But this is debatable depending on the user, I know.
