In our multidevice world, Amazon’s media store functions as what I like to call a “connector” — it bridges the chasm between otherwise foreign technologies.
This gets to the most important principle for dealing with an uncertain future: Invest your time and money in connectors. For instance, store all your important documents on the cloud-storage service Dropbox, because its business model depends on it working everywhere. And it does: The documents you create on any single machine are replicated on all your other machines, instantly. Similarly, when someone hands you a business card, you can snap a photo of it on the note-taking app Evernote, which also functions as a connector, letting you get at your scribbles regardless of which machine you move to next.
