Design = function + aesthetics

Ask your local programmer if he knows how to design user interfaces and invariably he'll say he does. Go ahead, ask. I'll wait.

You're back? Good. Now go look at the new iPhone. Has your guy ever made anything remotely that cool? Unless you're reading this from Cupertino, odds are he hasn't. The UI is more beautiful and, as near as I can tell from the demo movies, more usable than any other phone or music player I've seen. But I wonder, how much of the perceived usability is a response to the beauty?

It's becoming conventional wisdom that you don't want to make the demo look done. Excessive visual polish early in the process not only limits the feedback you get to comments about the superficial details, it also suggests equally finished interaction with the system. It literally makes it look like it's doing more than it really is doing.

I've avoided this problem in my career by not being very good at graphics, and avoided realizing that by not working with any real visual artists to compare my work to. Yes, I used to think I was good at it, just like every programmer. Eventually I realized that consistency and predictability were a poor subset of what an artist can add.

Now, whenever I make up a project plan, there is a task at the end for "Add Pretty". And my name isn't on that task.
