I may get a used one in a few years. Right now even when I buy a 3DS game, I end up spending my time playing the Switch instead.
The thing is though, I think the Vita is great right now for an emulation machine, realistically in a few years down the line chances are mobile tech will probably have introduced another device which does the job of the Vita a lot better, I heard good things about the Switch modding scene right now, but I'm coming up on the 100 digital games mark and don't wanna get my system banned by Nintendo.
Might actually buy a second Switch just to mod it, since I have a spare 128GB SD card now after upgrading my main system to 256GB
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
