Why vertical? That’s definitely the worst part. Maybe for DS games, I guess. The SP always gave me cramps for its thin design, and I’d hate to hold my phone with both hands.

Back when I was still buying new phones every time my old phone broke (so about 11 years back) I always liked the idea of a slide-out controller instead of keyboard for a touchscreen (just any modern) phone. Sony did the Xperia Play way back when, and if I was looking for a new phone at the time, I’d have gotten it. Nowadays I don’t even think they make the slide out keyboard phones. The next best thing I had was a little phone brace at the top of a bluetooth controller. It games great, but you it isn’t nearly as fast nor as portable. And even then I haven’t used it in a long time.

If I did still use it, I’d probably want one of these, and I think the price seems good. But I would also definitely look for a horizontal product, first.
