Writing this on a Fold 4 after coming from a history of Pixel devices.
Initially I loved the idea. So much room for activities with me at all times! A dream emulator machine and media consumption device! Look at all those power user multi-window layouts! SPen life! As time wears on though I find myself only relying on the inner screen for reading or long browser sessions. The SPen is in a drawer. I also dearly miss the Pixel-exclusive features. As a result, my next device will most likely be a Pixel 8/8 Pro coupled with an eink tablet.
For perspective, this was written on the front screen. I haven't cracked open the inner screen today.
