No, I mostly use it closed in a Twelvesouth BookArc holder, the connector gets caught on the top of the desk, moving other cables nearby bumps it and it drops out. A power cable coming straight out, like the other cables (Thunderbolt, FW800 & both USB 2) would work much better. Fortunately both MBPs use Magsafe 1 connections & are 85 watts, easy swap.
