It's interesting that I keep hearing about how fragile today's folding phones are, but have yet to see anyone offer any sort of proof that this is truly an issue. I get that more moving parts are more prone to failure, that's just common sense, but with official reports of 200k + folds (Samsung's
estimate for the ZF3, haven't found estimates for the ZF4 but they did say it was improved, other folding phone makers have said closer to 400k) estimated I think we are in good shape there. Its not like we are seeing an epidemic of broken folding phones, it's virtually a non issue. At the same time folding phones may offer better protection than slab phones in some sense, when the screen is folded closed it's much more protected than a slab phone for example. Edit: Here is the ZF4 fold
estimate.
Personally I highly doubt reliability is the issue going against mass consumer adoption, it's more the pricing, although I could see the *perception* of reliability as an issue, especially when word of mouth gets it wrong as in this case. Get these down to $1k and you'll start to see much higher rates of adoption. You have a great setup with a small smartphone and an iPad Pro, no argument there, except for me that setup falls apart when I try to stuff the iPad Pro into my pocket. That's just my personal use case scenario though, we all have combinations which work for us. But personally I don't want to return to the days of putting my tablet between my back and pants, or having to wear cargo pants to maybe be able to carry an iPad mini.
