Have you ever used an iPad? I get the feeling you don't really know how it actually works.
More familiar with iOS on iPhones though, but can't see how I'd do 'serious creative work' - which usually ends up involving large numbers of files that need keeping organised - on an OS that's traditionally tried so hard to hide the underlying file system from the end user.
And I've never tried connecting a camera or video capture device directly to an iOS device, so not sure what is or isn't possible in that area.
Can you explain how this squares with your other comment about how I couldn't possibly know how it works if I wasn't on the team who built it?
