Comments

Here are my criteria for a good interface:

Findable

Interactions are easy to discover, get to and repeat

(Unless they have the potential to be destructive or security risks)

Useful

The features actually make life easier by either:

Adding functionality

Combining sets of commands in a more intuitive way

Increasing navigability.

Desirable

The feature bloat helps users achieve tasks they care about

by decreasing the effort, frustration and knowledge required to accomplish their task.

Dan’s insightful and exhaustive list seems to fit into these categories.
