After reading Dear Nintendo…, a friend today asked me “How do you feel about the Switch?” Well, let's go down the list. Nintendo Account I can log into my account online, yes. Apparently, Nintendo Network ID is simply an OAuth provider for the rest of the Nintendo website. But you can also have a standalone Nintendo.com login. I deal with this stuff every day, and I still get confused on Nintendo’s website.
I have a Switch, a Wii U, the original 3DS, the original 3DS XL, and now the new clamshell 2DS XL.
