Raymarine C80 vs C90W

[SV Demeter]

Can someone point me to a comparison of these two devices? What, other than display size, are the features or advantages of the C90 widescreen unit over the C80? I have just installed a new Edson Vision II pedestal and the head is designed to accomodate a C80 display or similar sized unit. Edson has been telling me since August of 2010 that they are developing a new head for the Vision Pedestal that will accomodate a C90W display but at this point they still cannot tell me when the new head will be available. I bought the pedestal with the head backordered and can make due for a while but at some point I may simply say forget it and get the currently available head and go with the C80 which is a lot cheaper than the C90W.

Thanks.

Well beside significantly wider screen there's

(a) N2k ( seatalk ng)
(b) ais support control of ais500
(c) networkable to another C90w avoids E series for dual display systems
(d) software upgrade path STD C is finished software wise ( depreciated)
(e) minor improvements in user interface
(f) support for Rays digital smart radars
(g) extra interfaces.

Plus integrated GPS antenna and embeded charts for coastal North America/Europe/ROW depending on version sold in your locality.
