Hm... difficult question. I got a Pixel Fold at half price second hand. What MKBHD says about the Pixel Fold is absolutely true: it has the best outer screen/folded experience of all the foldables. Most of the time, I use it closed. And, apart from the abysmal screen brightness, it's a perfectly fine phone when folded.

There are still very few apps that support the full screen properly and while you can force apps to run full screen on the big screen, their automatic UI layout will simply blow up the lower and upper portions of their interface so that you don't see that much more.

Most Google app, obviously, have proper support and YouTube is definitely the primary use case for the big screen. Insanely, Google Maps loses features when viewed unfolded (WTF?). But even among the Google apps, though, most don't really use the space in a useful way. They often just put some hamburger menu permanently on the screen. Nice, I guess, but you won't bother unfolding the phone just for that.

Web browsing/reading is great on the unfolded screen. That's where the near-rectangular aspect ratio works best.

Honestly though, while I'm keeping an eye on what's happening in the foldable space, I think my next phone will be a boring old slab phone again.
