Had a Vita 1000 since launch (got the first edition bundle). Then years later I got a Vita2SD which destroyed the card reader (my mistake). So I got this JP Vita 2000 since I wanted one in Blue and the Vita 2000 is pricey.
Retroarch is a wonderful tool to play older games on whatever you have, though it’s a lot of work, the effort to get a device like a GBxCart or to hack a 3DS to get the ROMs is worth playing.
Personally I miss small form factor systems like the Vita, and hope that there will be a Steam Deck Lite one day that is pocketable.
