<P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 11pt; FONT-FAMILY: Arial">The original premise for Hermes was to combine functions to a single board (lower cost), now look at the picture of the prototype Hermes on the WIKI. It looks similar to Mercury, major components. I believe Mercury currently sells for $469, so then why is Hermes double that price. Only <U>major</U> differences I see are a different ADC, Ethernet PHY and connector, not sure if there is an Ethernet MAC or royalty based IP MAC core, and a new PCB. Do those items add up to $450 of added cost? I don't think it should and if they do then what can we do to reduce those costs? </SPAN></FONT><o:p></o:p></P></DIV>
