I finally got around to replacing my eight-year-old notebook. My ancient ThinkPad 600E worked reasonably well after several hard drive transplants and memory upgrades, but I was ready to move on. When it came time to configure my new ThinkPad X60s, I knew I wanted to include a built-in wireless wide-area network (WAN) modem. It lets you connect to the Internet over a high-speed cellular network.

The X60s is configured with a Sierra Wireless modem that’s locked into Verizon Wireless’ EV-DO network. Verizon has expanded its EV-DO coverage recently, so I contacted them about their 30-day trial offer. I called on September 29, and it turned out that was the last day the 30-day trial would be offered. Now it’s just a three-day trial.

Though Verizon’s connecting software (VZAccess Manager) is flakey, the service itself is excellent. I’m getting speeds that vary from about 300 kbps to 800 kbps. That’s not exactly DSL or cable modem speeds, but it’s fast enough to make mobile browsing an enjoyable experience. There are two downsides, however. The first is the price. You’ll have to pay $80 a month, or $60 a month if you currently have your cell phone through Verizon. The second is the restrictions on the “unlimited” service. You’re prohibited from streaming or downloading movies, music, or games. You also can’t use your notebook as a server or with a webcam.

Am I going to sign up after the 30-day trial period is over? I’m not sure. There is an option to pay $15 a day, which may work out better for me, as I’ll mostly need the service when I’m traveling to and from tradeshows.
