I’m over the knee jerk anti but this is not for me as it stands today and I’m yet to be convinced of any future personal benefits but my mid 20s son is gagging for one (an avid gamer). I’m probably in the same place now that my parents were at when I wanted the Binatone tennis to be upgraded to an Atari!
As for first generation I’m sure many of us remember the original video recorders. Ferguson VideoStar with a massive heavy battery pack was ours.
