I'm a road warrior for work. I've been using my MiFi on Verizon for a few weeks now.
If you don't know what the MiFi is, google it.
I am so happy with this device. It just works as it should. It is so simple, and for me useful.

I use many tools and test equipment for my work. I always judge the quality and usefulness of a new tool by asking myself this question: If I lost or broke it, would I replace it with the same thing? For the MiFi I answer: YES!
