I'm still running my Duo 2 as my work phone, it's fantastic for remote desktop sessions when I just need to restart a service or do quick tasks. The hinge doesn't crease but you do get a gap in video that's minorly annoying, but not a deal breaker. It's great for teams calls with scrolling on 2nd screen for info or referencing material. It's great for kindle, the book-like structure gives a pleasant feel while reading in two page format.
Unfortunately it isn't comfortable for phone calls. And having a hard close means opening for texts and teams and quick items does become bothersome and tedious towards the end of the day. And knowing it was killed puts a clock on it and always keeps me looking for a replacement. It will eventually go to the same pile where I put my zune and Microsoft bands.
When it finally dies I'll probably stay in the foldable format, Pixel or Galaxy. But I'm going to run it as long as I can.
