An integrated computational interface device may include a portable housing having a key region and a non-key region; a keyboard associated with the key region of the housing; and a holder associated with the non-key region of the housing. The holder may be configured for selective engagement with and disengagement from the wearable extended reality appliance, such that when the wearable extended reality appliance is selectively engaged with the housing via the holder, the wearable extended reality appliance is transportable with the housing.
