How can i gain mobility for my laptop as expeditious & simple as possible lacking going thru my phone company?

Answer:

Depends on what you plan by mobility. 56K dialup? Just get a PCMCIA modem and an tale from a dialup ISP for $6 per month. Cellular wireless? That might be a little tougher. WiFi? Need on the other hand ANOTHER kind of cardbus card for that one!! Oh, and an unsecured WiFi hotspot or the WEP push button for a secured one.
Get a Wireless USB adaptor for your laptop.

Most places nowadays are wireless hotzones.
