Suction cup damaging canopy?

Sorry for a bit of an aside on this topic but I dislike mounting anything to the canopy, frame or glass, as it could (maybe a big could) prevent the canopy from ejecting properly. Of course this would only happen if there is a power/data cable involved. Now I will admit that this would seem to be an unlikely event when a PDA/PNA has a USB connector which SHOULD release easily. It was probably more of an issue with the ubiquitous cradles holding Compaq PDAs of days gone by with surprisingly strong cabling. But if we have to eject we don't want anything hanging things up. Right?
