A method and system for transferring a computer session between devices, such as a land-line device to a wireless device. A user launches a computer session on a first device, such as a personal computer. The user may then selectively transfer the computer session to another device, such as a wireless device, through activation of a triggering signal or other transfer request means. In response, the context of the computer session is determined as it is being performed on the first device, and corresponding context data is transferred to the second device. An applicable application on the second device is opened and loaded with applicable context data to continue the session. Several session transfer mechanisms, including use of an online service, proxy mechanisms, and peer-to-peer communication links, are disclosed.
