I just picked-up my adapter from a local Apple store. Has anyone actually used one of these yet? The cable itself looks fine, but I'm a bit worried about the size of the empower connector - about 2", 3" if you want to bend the cable without kinking it badly. Given the location of the empower port on United's c-seats, this could be a problem. That said cable length looks good, about 56" connector-to-connector, and it generally seems well-made. (Unfortunately the MacBook Pro it will power has not yet shipped.)
