I figured you have much more.
I personally have to be choosy with my limited space. (5-6 cabs)
I hear ya, and those kind of Ccabs were designed to open the doors to extended play. Its cool to see how they are like slot machine in Asia where people will just sit at them for hours on end. The game styles prevalent on those machines work better for sitting as well.
I guess where I differ is I look at classic games, ergonomics never bothered me with a few exceptions such as parascope games. I wanted to be at the ready. I love the feeling of chucking in a quarter, squaring myself up to a cabinet, and frantically try to keep going as long as possible. I still get that vibe with a stool, but in a chair, my posture quickly slumps to couch gaming. It's just weird. Like, the reason for having a cabinet just disappears.
