I've been reviewing laptops for years here at Tom's Guide, and a few of them share a unique feature that's still pretty rare in portable PCs: They fold.
Foldable laptops aren't quite as popular or as widespread yet as the best foldable phones, but I've slowly seen them grow from wacky proof-of-concept devices to a clearly defined product category. A few years ago the only foldable PCs you could find were prototypes being demoed at CES, but now you can go online and buy foldable laptops from major vendors like Asus, Lenovo, HP and more.
