with his iPad, unfortunately my two devices have not demonstrated any thing near what he discribes in terms of reliability.
I am running three iPads and don't have a problem. I had more issues with the external GPS going flat and losing connection than I have ever seen with any if the iPads. I have had every generation of iPad and am now on an Air 2 with no issues.
The extra utility from having the 3G version with Gos outweighs the minimal extra cost and improves the functionality no end.
Think outside just using it for aviation. Mine gets used for all sorts of stuff that uses the GPS. Having to cart around a seperate GPS would just be a pain in the ass. And at the end of the day if you are as unlucky as A and C seems to be you can always uses an external one as well......
