The Heart Of Gold. Think about it. You could do anything as long as you know the direct probability factor of it happening. Even go back in time and punch Douglas Adams for screwing up the ending of Mostly Harmless. That seems like a fair trade if all I need to do live with a gay computer.
Seconded, I hated the ending.
Anyway, I choose not only the Heart of Gold, but all kinds of interstellar/intergalactic spacetravel. Being limited to this small hump of rock, I feel so confined, I wanna go out there, explore the vast universe (well let's start with this galaxy huh?).
Honerable mentions go to Holodeck technology, only without a 'kill switch'. I don't know who wanted to install
that, but I rather not take risks, and keep my ultra-awesome game console (you won't get any better) safe.
