Mine was a V2, I got it in grade three. And then it broke a few months later. I still have it, sometime I pull it out and remember how fun a Tamagotchi was.
I got it as an early Christmas present from my mum, and she told me to hide it from the rest of the family until Christmas day. I lasted about a month. It was hard to hide it because back then I didn't know how to turn the sound off.
I couldn't vote in your poll. My first Tama is an ancestor now, but was brand new at the time of purchase. It is a royal blue P2,yellow buttons, and black around the screen. I got it in 1997. It still works great.
My first Tamagotchi was a v3; I got it for Christmas, and I believe that if it weren't for that particular first Tamagotchi that I got from a Secret Santa, I wouldn't have my two other Tamagotchis now.
