Have used mine for 8 days of flying so far. The recommended technique is to use the battery pack to power the tablet during the day. I've done that, and as an FO, the cord only gets in the way of my drink. The tiller might be an issue for a captain (or stick for Bus drivers). If you use the battery pack, your only have to charge that each night. Seems much better than RT, quicker and less issues than the Dos...
