Does a v3 count as a vintage? if yes, then I had my first vintage when I was about 10 years old. It was a white v3. It got serious water damage as it fell in the toilet... *sobs quietly from the nostalgia*
My first vintage was a royal blue P2, it's crazy to think how long ago I got that little guy, but he still works just fine. Fun fact, my now favorite tamagotchi Kusatchi (the funky little dude on my avatar) originated from the P2.
My first vintage Tama was a magenta P1 that I got from a Finnish website quite a few years ago. I've played with it just once, since I accidentally ruined its screws with a screwdriver too big. I haven't been able to play with it since then, because I have no idea how to get the screws out. They're so small.
