Perry...I've been on cell for several years on my laptop, using AT&T's 3G network. Not as fast as cable/dsl, but fast enough and complete freedom. The Sierra cards seem to work best for their netwrok.

Check the major networks (AT&T, Verizon, etc.) and see which provides the best coverage for you. I'm good just about everywhere, but it is a little weaker at my house. You can buy portable external antennas to help.
