It is not about need but about choice.
Being in an airport is not like hanging out at the local park. There are no birds singing or fresh gentle breezes caressing your face. It's many people milling about with the accompanying background noise, Homeland Security Threat Level "Orange" (has this ever changed?) and passenger Thelma Jones, get to your flight or you are S.O.L.
I fly once every 3 weeks or so and I carry only my laptop, my book and a magazine. I find it difficult to read for pleasure within the airport. With an Internet connection, I can get some things done like pay bills, email Mom, view Slashdot or see if my epic item sold at the AH
Yes, I could wait. I could sit at an airport and watch CNN while little Jimmy round around his exhausted parents, waiting for my delayed by 2hrs connecting flight.
I prefer something else.
