But when that day comes, you’re going to need to transfer files back and forth — and if you’ve got a Mac, things aren’t going to be quite as straightforward as they were on pre-Android 3.0 devices.

That step has managed to confuse just about everyone we know who’s acquired a 3.0-device so far (read the manual? LOL! NERD ALERT!), so consider this a little future-proofing PSA.
