I'm already locked in to the family plan for four more years. The XLR is the only "single use" XM unit we own.
We love our Delphi SkyFi units. We have a cradle in my company vehicle, my wife's company vehicle, one in the den hooked into our home's entertainment system and one of the portable boomboxes.
It appears the rate increase will come with the inclusion of two premium service channels allowing them to justify the added cost and at the same time hopefully generate additional cash flow on the front end.
