If I was locked in solitary confinement...

..and I could only have one possession with me, I would choose my computer (with working wifi).  Yeah, okay, it seems obvious, but picture this: you're all alone encompassed in gray walls.  A crikety cot with a flimsy white sheet are among your only comforts, and no one is allowed to visit you.  Would you take a book? a TV? a favorite mattress?? No, not me.  I would bring my computer because:

1) It would allow me to connect with the outside world

2) I could watch shows, movies, YouTube

3) I could read online, also listen to books with my Audible.com membership

4) I could write

5) I could still skype with my loved ones.

6) I would have a calender app so I wouldn't have to mess up my nails scratching tics into the walls to count days.

Our computers are all in one entertainment machines, and I could not live without it.
