    Not really. Xerox produced a much earlier system with a desktop and a windowed GUI. Apple's and Microsoft's systems were influenced (if not actually "inspired") by Xerox's system, which was based on earlier work still.

    Useful  information, suprised iPads do not all have GPS, I would have assumed so as the iPhone does  - I would have fallen into that trap.  I have used the iPhone with Navionics app, very good, though the bigger iPad screen would be even better.  Whilst being very inexpensive, you cannot download charts, which is I guess why they market at a discount - to draw you in to the full ££.
    That said I really do not get on well with the iTunes platform, much prefer good old Windows.  Which is odd as Apple invented the windows approach.

    Only the Wi-Fi + Cellular iPads (including mini) have GPS. The straight Wi-Fi iPad doesn't have it. By contrast all Nexus devices have GPS.

Which is fine if you're within cellular range, but is it accurate? For this reason, We bought a bluetooth GPS to receive satellite data. 

    Do you mean that the iPad might not have a real GPS and wouldn't work offshore?

    just caught up with this thread!

    ram mounts are excellent, we have the ball fittings all over the boat and lock down the iPad (and Bluetooth speakers) wherever we want for whatever use we're putting it to. it seemed false economy to buy an expensive piece of kit without buying a means to secure it securely on a moving boat! They also do holders that work with the mount system for loads of equipment including laptops. probably the best set of gadgets we've bought for the boat.

    No one seems to have mentioned Garmin Bluecharts App? late 2012 garmin offered this which was what prompted our iPad purchase. NZ to off the coast of Brazil for 49.99£, fully integrated with Active Captain, and can talk to Garmin Bluechart plotters ( we don't have one)
    This is our back up to our laptop running opencpn. Disadvantage is the two systems can't talk to each other to upload waypoints, they are completely separate. Suppose that could be an advantage too! Stores routes, photos, naming of waypoints, shows local information from offline active captain database.

Chose Dual because unlike the garmin (December 2012) Dual has a dedicated iPad app to monitor signal accuracy and battery. Also comes with non slip and wrist holders.

    As far as I understand it, you don't need the wifi or cellular versions if you have a Bluetooth GPS linked to the ipad as you'd be able to navigate using satellite. anyone know differently?

    Here's a funny thing - as I was leaving Cordova, some weeks ago, the iPad failed to get a GPS fix. That was OK, I could still refer to the charts and use my trusty Furuno GPS for fixes. It stayed that way until I was in Pelican, when the iPad got an approximate fix from the cellphone system, and then failed to fix when I went out of range again. A few days later, in a remote bay with no cellphone system, the iPad GPS started to fix again. All the time, the Furuno had no difficulty in fixing, so the GPS system itself was operational. I can only put this down to the iPad needing to have an approximate idea of where it was before it could reload its almanac. But why did it fail to fix in the town of Cordova??? And why didn't it get an immediate GPS fix when I was in Pelican???

    There are plug-in external gps devices for iPads. I think Navionics recommend Sea Elf. Google it.

    Just to clarify:
    You need the iPad model with both Wifi and SIM card to get GPS. The Wifi only model does not have GPS. However, the model with the SIM card does not need to be connected to the 3G/4G network for the GPS position finding to work.
