If you are on the road a lot, and find yourself in the occasional Starbucks, you can get (nearly) free daily Wi-Fi for the cost of a single cup of coffee each month. Get a Starbucks Card, register it online, and use it at least once a month, and you'll get two consecutive hours a day of complimentary Wi-Fi.

Of course, if you've got an iPhone, or want to pretend you do, you get the free access anyway.
