If they are marketing;
I'm sure not seeing any marketing efforts in trade magazines...I'm looking in every resort mag, hospital mag, cruise mag..nothing. Even checking with tour managers..no word, or knowledge of..
Our guy was at the Midwest Bus Tour Conference recently; didn't see or hear a thing..
Of course, probably most of those mags were put together a month ago, but..hard to get orders if there's nothing out there about you...
BTW...Cost maybe one thing, but my guess is, is that most content for these gizmos will be wireless/satillite...everything transmitted within a certain range...JMHO
