Have you not imagined the idea of being able to have internet access on your laptop at all times no matter where you are? For ages, the only way to do this was to get an expensive serial modem computer kit ($200) for your cell phone and use it to dial into a dialup ISP at approximately 9.6-19.2 kbps. As you can imagine, this was terribly slow and expensive. Factor in consistently poor reception, and the experience was pretty painful.

Now that 2G and 3G cellular service is available, that dream has been coming true. 3G speeds are usually in the neighborhood of 100 kbps, and companies. All the major providers offer PCMCIA cellular cards for laptops, most phones have fairly inexpensive connectivity kits ($50 or less), and some phones even include built-in Bluetooth support for cable-less connection to Bluetooth-enabled computers.
