Bah, the wishes in this thread mostly suck.

1) Immortality
2) Ability to change form
3) Teleportation

You won't need much else.

Time travel is interesting but it might be more trouble than it's worth.

I totally agree. Of course you would have to have some way to die if you needed to. You would be sad when people died, but you would get to see where mankind ends up, and that would be better than any downside I can think of.
