The description relates to hinged devices, such as hinged computing devices. One example can include first and second device portions and a hinge assembly that includes spaced-apart parallel first and second hinge shafts. The first portion rotatably secured relative to the first hinge shaft and the second portion rotatably secured relative to the second hinge shaft. A tensioned synchronizing element synchronizes rotation of the first portion around the first hinge shaft to rotation of the second portion around the second hinge shaft.
