Matt,
...I have had a Verizon wireless card for my own laptop over a year. Data Service in metro areas like Omaha and Lincoln is good, but rural areas no service/slow service.
...When my company closed our branch here and we began telecommute they set me up with a Data plan through their cell provider, Alltel to access internet on the co. laptop. It has worked very well, at speeds almost 2X Verizons, and it has worked all over Nebraska, even rural areas(alabeit a little slower, to be expected though)
...This 'add-on' data plan adds about $20 to the cell phone plan, seems well worth it, for internet access any time. The cord supplied with the kit plugs into laptop USB and that cord has a duplex plug built in to keep the phone charger hooked up up.
...I'm no 'techie' but did an online speed test with the wireless card and cell modem:
wireless card 349.7 Kbits, Cell modem(alltel) 486.5 Kbits
Beats dial-up anyways.
