I have the Fold, and while, yes, it's a big investment in, Samsung takes the sting off of buying a potentially fragile phone by making it cheap as hell to get it fixed/replaced. I pay $10/month for their premium insurance, which covers just about anything, and it's like $200-250 for a full replacement phone.

In terms of increased utility, it's amazing! I honestly can't see myself ever going back to a normal size phone. It feels so nice to read on this wideass screen, able to see almost entire articles without having to scroll. Youtube and such on it is great as well.
