The tools featured under "Cool Tools" will be primarily those that i have test-driven personally. But Scott Bassett's Verizon 3G Mobile Hotspot Service Mini-Review is well-written and this service really is a cool tool. The $20 per month charge is quite reasonable. Since he was trying it out at the same conference i was attending in Grand Rapids, Michigan, I figured I probably walked through his wireless cloud at some point. So i had some contact with the tool. But seriously, this is a nice review and one of the really nice features of the Droid X is this ability to call the provider and turn on the wireless capability to provide Internet access to five devices on demand. Of course, depending on your plan, you might incur additional data charges if you provided service for four or five devices for a lengthy time.
