I don't intend to take pictures with it, the games I play on my iPad won't benefit from the A8X and I don't really care about entering passwords on my iPad much. These are all things that were an issue on my iPhone but are now solved.
Now, as to the rumored Pro: there's no doubt that Apple is going to do something with the iPad line. It may not be a larger "pro" iPad, but it will be something. Even if it's only a redesign of the enclosure next year, it'll still be a change. So, again, FOR ME, the Air 2 is not a significant enough upgrade to warrant a buy. I'll wait until the next revision to see what Apple does with the line... because they will do something with it.
