Clive Thompson on using multiple devices to work:

In a sense, screens are beginning to absorb some of the cognitive ergonomics of paper, one of the oldest reading devices of all. With paper, after all, we’ve always put down one document and picked up another, shifting our attention organically. And as Abigail Sellen and Richard Harper note in The Myth of the Paperless Office, spreading out papers on a desk lets our eyes easily roam—a property hard to replicate on a single screen. Now the plunging price of hi-res mobile devices means it’s possible to own a few of them.

“A few of them”? Hmm, I don’t know about that. It makes sense to make use of the device you have already, or to add in a tablet. But if the idea is to add in multiple tablets to better replicate a paper desk workflow, then — umm — why not just use paper?
