I am, for the first time, posting from an airplane during a flight using an inflight connection!
This opens a range of possibilities.
I have a good connection, fast. I was even able to stream my satellite dish via SlingBox (blessed be slingbox) and access the nerve center computer at home.
For longer flights, especially when I have a writing deadline this could really help.
You can access the Internet from a laptop or a handheld. I am on my iPhone, for which I have an external supplemental power pack. Next time I will use my laptop.
