I had 800XL but with the joystick from the picture. It didn't had micro switches so it was very quiet. I could play while father was sleeping on the couch.
We had a 400 before that, and that one was ... less sweet.
I was too young at the time to appreciate the greater computing ecosystem, but today, I find it fascinating. Growing up, we too had a 400 and then 800, and that’s where I first started. And now you can find YouTube videos building a computer from scratch using the same chips.
It's not an exaggeration to say that one third of the ads in contemporary Atari magazines is for some sort of keyboard replacement for the 400.
