I received a Switch 2 and tried "transferring" or copying my local Switch 1 accounts and save-games to the Switch 2.
But apparently you can only do these kind of things using user accounts linked to a Nintendo-account, which I don't have or want.
So, guess that story stops there.
On the Switch 1 you had the option to transfer any account to a different Switch. But this option was removed on the Switch 2.
I assume to prevent piracy or something, like sharing a local users save-game and probably to push more online subscription services.
So, if you have a Switch 1 without a Nintendo-account: you need an account to transfer your user (+save-games) to the Switch 2.
It also appears you cannot transfer a user from a Switch 2 -> Switch 2. I assume you need to login and use cloud-saves for that instead.
Note: So, this means you cannot copy a user after you started using your Switch 2. Transfer is only available during the Switch 2 setup.
First impression of the Switch 2. The screen is much larger, obviously, and brighter. The controls stick well, they're magnetic now, otherwise feel similar. The unit looked more slim.
The GUI is similar to the Switch 1, so experience-wise you feel right at home when switch-ing from Switch 1 -> Switch 2.
And having two USB-C ports is nice, but I still used the one on the bottom as usual.
