Mobile Office
As ye olde parents are away on travel to Italy, it has become Pat's
responsibility to taxi around the kids. While some events are long enough to
justify two trips, others are short enough that it doesn't make sense to
come back home in the meantime.
Enter the mobile office. My car has already proven itself to be a useful place to sleep when everything is folded down. Half folded-down, it makes a great place to set up "base camp." Hook the laptop up to the inverter, use the handy-dandy sound system remote lying by the seatbelt buckle to control the music, and it becomes a useful hacking-mobile with tons of leg room.
In fact, most of my latest project, the NetworkManager Editor, has been put together on the back seat of my car waiting for tae-kwon-do to finish.
