Convenience and easy of it being worked into your daily life is important, I bet some people need to see that in the way it's shown here to see how much better the Trax can be.I guess they're just trying to show the convenience it can offer.
Also good if you need to do work on your laptop from time to time on the go and your trax can give you the signal you need to access the web.
But of course you can also do that with your phone.
