I remember, many years ago, Nakamichi made a clock radio that integrated two clock radios together to create a stereo. They discontinued this product long ago, but seeing the Cue R1 made me think of it again.
Instead of offering the R1 on it's own, OR simply with an additional speaker, what if you were to create, essentially, two R1's that could be connected so that both me and my wife could have a full clock radio/iPhone dock on each of our nightstands, but the speakers would be connected to provide stereo sound.
There are several manufacturers making what you are currently offering (a clock radio with the option to add another speaker) but no one is offering two actual clocks/alarms that work together to create a stereo.
What would it take to modify an R1 to simply make it a "slave" to the first one, but adding a clock/alarm and iPhone dock? It might be called the R1S (for slave) or R1C (for companion).
Does this all make sense? I'd love to see a product like this.
