ICBMs have a habit of not being recallable. Once it is in the air, the only abort possible is destruction of the missile. Unfortunately, that still leaves a lot of shrapnel on a ballistic trajectory to the target.
They get to the target in 30-60 minutes. If you are so confused that you're going to change your mind in 30 minutes, don't launch.

In most cases, you're talking about a few minutes before and during takeoff and a few minutes during landing. During that time, read a book.
I've certainly used tablets, phones (for apps), and laptops all other times during flight.
There is no one on this planet who can't live without the Internet for the duration of a flight. If you are so insanely important, buy the plane's service.

Personal analytics appears to be what was earlier called "narcissism".
