Cogito ergonomics sum

I think therefore I am – ‘the cogito’ – is Descartes most famous contribution to philosophy. I might doubt everything else; that I am thinking is a certainty.

But thinking – and doing something about it – requires a comparative absence of distraction and ideally a modicum of comfort. And that’s where design comes in.

One of the reasons I’ve written less in the last few weeks is my new shiny iPhone 5. In many ways a splendid device. But more is sometimes less. And I find I can’t write on it.

It’s too big. I can’t reach the top corner ‘action’ buttons. It feels like it’s constantly going to tip over backwards – and tumble and smash into small, beautifully machined Apple pieces.

So I’m back tapping on the iPhone 4 (which I couldn’t give up despite a generous financial offer from a good friend). Fast, fluid, typing is a doddle again.

Ergonomics matter. Hard to think when you’re uncomfortable, hard to write when your hand hurts.

Technology isn’t always getting better. The iPhone 4 is my perfect writing device. Like Hemingway’s Moleskine or Remington’s typewriter, when it comes to writing iPhone 4 is the classic.
