Ok, so can you plot a gps route on a web based site on an iPad or an iphone and then save the file?
I think it is a big fat no. You can of course do it on a MacBook, but also on a Dell for half the price. No Linux or knowing what goes on it the box needed, not even much computing done by the computer as it is done by the website, but shows you just how limited the iPad is. Watching films, browsing, emails etc, but for the moment that is it.
