I'm often on the road, traveling to different places for meetings. When I'm not driving, I'm often working on my laptop. I stay connected by tethering with my smartphone. It's great to have EV-DO speeds when I'm stuck in traffic because I can download large attachments and stay productive when I'm out of the office. Someday, I may eventually switch to using the built-in WWAN (Wireless Wide Area Network) that's in my laptop, but for now I will save some money by tethering when I need to get online.
