If your labor is greater than the 50k cost I would say it was a rip off and a bad investment
Probably not. The accumalated bug fixes over the course of 30 years have probably cost them much more than the purchase price. If the system were to be redone from scratch, it would bring with it a whole other set of bugs, which would have to be fixed.
Angry Birds Space for PC has been released, and works (or at least the free demo does) under WINE, allowing unix users to play as well. Having more than one source of gravity makes the game considerably more interesting, not very much more challenging.
