Simple is better than complicated

All design and engineering decisions will be taken with the following principle in mind:

Simple is better than complicated.

We will always try to eliminate choices that the user must make. Every bump on the user experience must be relentlessly sanded down. Our customers will say: "It's the easiest thing in the world and It Just Works." No jargon will remain in the user experience, anywhere.

Que bom seria se todos os sistemas fossem feitos assim, não é?
