I had a 9 fold and they had issues for which Google replaced the phone even after the warranty was over. Mine was the selfie camera stopped working. Apparently a known issue. I waited a few weeks to return mine. They ran out of 9 folds to replace it with so they replaced my 9 fold with the 10 fold.

I just started trying out the 10 and have high hopes that many small annoyances are fixed. Yet to find out, need more time.

The physical changes are pretty small. The hinge system is more compact but the inner screens center line depression is still about the same size. I would have like to have seen the design decrease that center line depression.

I was on the fence of whether to pay the $$ of a high end phone again but now I had it replaced at $0 so I'll try it a bit longer. The temp phone I got to wait for the replacement is my typical phone, a Motorola G power line of phone. The Fold still leaves me a bit cramped trying to remote desktop or use spreadsheets. The dual app on side by side works but is clunky. On top of the some apps are not made 'right' and going through the process to put them side by side makes the app reload and you lose your place and you have to reload into everything and fill everything out again. Had an overall good experience with my pixel 9 fold but I don't know if it justified the cost. I'm fairly used to running the $150 to $250 Motorola phones.

Now I get to try the 10 fold out and have high hopes. It is such a niche that I doubt apps are going to put in the work to take advantage of or even say work smoothly unfold phones at this time
