Nothing like free wifi at an airport where you might be waiting for what feels like a lifetime to get a flight. At Denver, I was suprised to find free WiFi. It connected pretty fast, and then I noticed how they are paying for this. Simple. Through advertising. I know it sounds very 1995, but, for a frequent traveler like me, its a boon. I don't mind the one inch wide banner on the top of the browser as long as I get the job done. Since I travel mostly for business, I can get reimbursed for paid WiFi, but the hassle is too much -- pull out the credit card, enter all the information, wait for it to process, then get access to the internet (sometimes a weak signal, not worth the money), and of course, remembering to expense it a month later when I do my expenses seems hardly worth it. For now, I am blogging from Denver International Airport, and owe it to the colorful banner ad you see in the screenshot. Are you going to ever do this Boston Logan Intl Airport!?
