Huawei’s Mate XT 2 unfolds into a 10.2-inch display, but its US$3,500 price puts this trifold firmly in luxury-phone territory. A South China Morning Post reporter spent a week trying it and describes a paperback-weight device that drew curious looks on trains and in restaurants.

That makes it an eye-catching example of how far foldable phones are stretching the idea of a pocketable screen. The obvious catch is the price: this is a look at an expensive piece of hardware, not a case that everyone needs one.

Discuss: Would a tablet-sized screen that folds into a phone justify a US$3,500 price, or have foldables yet to make the case?
