Proporta (UK company) sells a retractable USB cable that does both sync and (slow) charging. They say it's compatible with the TJ-27. One of my primary annoyances with the TJ-27, compared to the Tungsten E, is the bulky charger, sync device. With my T/E I could travel with my USB travel mouse and use the detachable rectractable USB cable to charge the T/E and sync it as well.
This isn't quite as neat as my old solution, but it's pretty close:
Linear Mode
