How is the home plan $55 of clearwire work for you?

I always wondering about their promotion on this $55 a month for two, both at home connection, and the to - go portable USB modem? So, if I pay $55, I can use the home modem device connected to the internet, while my sister can use the USB modem at remote place or on the road the same time, without signal interfering or slowing down the DSL speed? What is your experience with it if you have clearwire $55 promotion?
