Once I transfer all the stuff I can over to my Switch 2, I'll give it to my nieces and nephew just like I did with my 3DS.
Before I do that, though, I'll have to take all the joy-cons and pro controllers I have for them to get checked and out make sure none of them are drifting.

Edit: But before I do that, I should really finish the backlog of games I have on it.

I suspect I won't be doing much of anything with my not-quite-launch vintage Switch, seeing how it's pretty much useless for portable mode as it'll no longer properly pick up or charge any Joy-Cons. Still works okay enough for television mode, so it might come in handy for playing any games that have show-stopping bugs on the Switch 2, at least until Nintendo sorts out any issues.

I will sell the one I am currently using and keep the limited edition one for collection!

keep. i dont like selling sentimental products (i get emotionally attached to my vg consoles.)

I'll use it for Game Share with my girlfriend and to play the most light weighted games I have (mostly indies).

I'll keep my Lite for Indies and gift the 8 year old day one Switch without Joy-Con's to a father from work with many kids and just one console in their household at the moment.
