The description relates to hinged devices. One example relates to a device that has a first portion hingedly secured along a spine and a second portion hingedly secured along the spine. The example can also include a first spine cover secured relative to the spine and extending into the first portion and a second spine cover secured relative to the spine and extending into the second portion. An extent to which the first spine cover extends into the first portion and the second spine cover extends into the second portion is controlled by an angular orientation of the first and second portions.
