Whedon's "Dollhouse" series was a pretty good take on this topic. The show opened with the premise that brains could be saved, generated, and overwritten digitally. The focus of the show was on a company that hired people to upload their consciousnesses to a drive, and then exist as "dolls" that had their minds written over with both synthesized and real consciousnesses and rented out to clients by the hour, as whoever the clients wanted them to be. Did a good job of exploring the broader implications of the tech from a relatively narrow application of it. Impressive acting from the main cast as well, each of the "dolls" had to demonstrate a huge range.
