Alex Payne – al3x's Rules for Computing Happiness:

"Do not use software that must sync over the internet to function. [Ed.: I'm looking at you, Microsoft Outlook.]

[…] Use a plain text editor that you know well.

[…] Do not use anything other than a Mac at home and Linux/BSD on the server.

[…] Buy as large an external display as you can afford if you'll be working on the computer for more than three hours at a time."

(Via Marco Arment.)
