You'll find that some services require annoying pop-up advertisements to appear on your home page, but that's the price of a free service. Develop a strategy to find access to the Internet. As the Net becomes more a part of everyday life, it's becoming increasingly easier to access computers connected to the Internet. Your public library may offer Internet service. This is an excellent list to consult before you travel.
Some businesses offer Internet access.
National chains such as Kinkos, or business centers in major hotels, airports, or conference centers, may offer Internet access for a fee. Some airports provide kiosks from which you may access your e-mail, but in most cases, they're expensive. If you can put together a set of Web services that you need, and develop an ability to find and use public Internet access, you may achieve a truly mobile Net life. In fact, if you're willing to use resources for mobile Net access all the time, you wouldn't even have to own a computer.
