If it was permanently broken (perhaps a future we may have to look forward to), then I would start breaking open my impossibly large collection of things. From growing up and having that godawful internet speed (as I've mentioned in at least one other post), I've accidently conditioned myself to hoard anime for my breaks, so I have something fun to do...except that didn't stop when my internet speed increased 1200x from that time. So as of my calculation of 2 years ago (when my speed was only 300x growing up), I have enough anime that I haven't watched to watch continuously for over a year and a half 24/7. That doesn't include the plethora of games, nor the multitude of skill learning tutorials, nor my 3D/graphics imagination :3 Of course also not including the fact that my Dollfies keep me entertained for hours at a time, even more than hours if I'm making an outfit for one of them.
Temporary Internet crash would apply to the above too though. xD
Now what would you do if your Computers were all broken and didn't have the money to repair them to a functional state?
