Despite my comment above, I actually agree with you. People buying a Pixel Fold for the outer screen should just buy a 7a and save themselves a grand and a half.
To be honest, I've never used a fold, so I may actually be totally fine with the outer screen... but from my flip use, I do know that you DO need a workable outer screen, because you just don't have the ability to unfold it every time you need to do something, and that is an even bigger issue on something so large. Everyone is different, though. And as I said, I could be wrong... I thought the S-Pen was stupid until I got one and found it intermittantly useful... but £1800 is just too much money for something I don't think I'll like when I've already got something better in every way but screen size.
