I have a Garmin GPSmap 76CSx, purchased it a year or so to aid with sailing as I liked the blue chat maps. It's a great device, waterproof, mapping is good, ease of use is good. I also use it on land as well.

I've also got an iPhone 3GS and the GPS is pretty good, but if you don't have internet access then lookups on things are not going to work, and with a dedicated GPS that has the mapset installed on it, that's not a real big problem - of course items not being totally up to date could be an issue.

If Garmin decided to have an iPhone viewer and enabled me to use my existing maps then I would seriously consider ditching my 76CSx. Of course a waterproof case for the iPhone would be required as well, but that is probably available.

I am going to look at Navionics as I believe they do have an iPhone viewer app, and they also do marine mapping, so perhaps switching to a different map provider may be an option to go totally iPhone.

One wonders if they'll have hand gestures in the next revision. The "Find Porn" one could simply be the use of the "wanker" hand gesture, which is most appropriate. :D

"...stroke the epeen"? Is that similar to spanking the monkey?

Don't forget... Don't move your offices to from Ireland to another country whose taxation rate is low/none-existent to save yourself money. Unless of course the savings made by doing this are going to all those poor, starving types you always wail on about. The day you give up all your money, property and worldly belongings and donate the proceeds to these starving masses, and then you live in a box on a street, better still, sod off over to africa to live, is the day I'll pay strict attention to the cause.
