You nailed it. This Pro version of the iPad isn't really very "pro" when you check into it further. It's a larger screened version of what we have now. Better speakers and some more RAM. Processor bump too. That's it. No hard connectivity, overpriced, no file system access, etc, etc. As much as I love iOS and all that, this devic should have come with some type of "power" version of iOS or a light version of OSX. Or something.
The keyboard and pencil are too expensive as well. I don't see why a pro level user wouldn't just get a MacBook at this price point. Or, a powerhouse refurbished rMBP. Same money. Oh well.
