Slingbox question

[Mikenk]

I understand people really like this; can someone explain to a non-tekkie what it does?

I have a TP2 and Mac laptop. I spend lots of time tethered in airports and in European cities with little access to American TV. Is that what slingbox does? is it just for the phone or also the laptop? I hate to miss NFL games when in Europe or traveling; will it help here?

I know I can research this myself, but it would be great for someone to summarize for me.

Thanks for any guidance.
