Lordy, I ain’t never heard about one of them before. You’re a genius!

Now look around your office and see how many people are using them. There’s not a single person in my sales office, whether sales or engineering that bothers with a dongle because we actually have a well designed, fast wifi network. It’s called “reliability” and you and your company should look that up.

From the responses here it sounds like many companies need to do the same.
