First, I have to pick a radio.  

Next, I have to pick some very technical parameters in order to use the radio in the best manner for my application.  Then, I have to pick a chip or module from some manufacturer.  

The challenge continues with who has the best firmware, tool, and technical support.  And to top it off, we must talk about material cost, regulatory requirements, antennas, layout, anechoic chamber testing, etc.  

Urgh.  If I could just plug it into an RJ-11 phone jack or a serial port somewhere.
