well i wouldn't intend spending that much time in it. just a classy way to warp somewhere nearby. like a car. do you poo in your car?
Why not? Get a runabout, and you can use it for all the same things as your little shuttle, and you can also spend a week on Mars if you so desire.
Besides, why wouldn't you want to spend your time in something that has a replicator and the sum total of human knowledge. And hey, chick magnet too.
