Counterpoint to the counterpoint, I have a Z Flip 4 and I love this thing. Yes, the internal screen is easier to scratch but since the screen is closed when you're not using it, it's not really an issue unless you're Edward Scissorhands. Yes, there is an extra step to using the phone proper but the small outer screen lets me do all of the "need to check my phone real quick" stuff without needing to open it, like checking the time, notifications, weather, timers, and Spotify. Besides the cool factor, though, I have to carry a phone for work in the same pocket and this form factor makes that easier with less risk of scratching either screen. I won't say it's for everyone, but it's perfect for my use case.
