I routinely transfer HD video from my Android devices to a
couple TB external slim HDs.
I'm not disputing Android. Just saying that copying a photo or
powerpoint presentation or something from an iPhone/iPad directly
to a USB drive, not the easiest thing in the world. I haven't
tried it, but apparently there are wifi USB drives that'll do it
(maybe not the photo, because Apple's a litle funky about them).
