Hmmm, well when I was paying $60 per month for my dedicated and unlimited line, it just seemed like I was throwing money away. I use the connection, on average, probably about one week out of a month.
It's discouraging to hear that 5 GB can go quickly, but keep in mind that I do almost all of my work on my desktop with a DSL connection. This would only be my secondary / travel connection. Plus, there is a tool that allows you to see your actual usage. Most places that I travel to have some sort of wireless connection that I can use, so this secondary connection is literally for my vehicle, clients' homes or offices, and hotel rooms that don't offer internet.
While I dislike the idea of being limited on data transfer, this just seems like the best solution for me at the time. I'm glad to hear that other companies are offering this service, since my contract has less than a year to go...but I really do like Verizon's dependable coverage. Guess I will see how it goes.
