My wife is always complaining to me about technology, “I just want it to work.”
Why developers can’t get a grip on good UI baffles me.
A good example of UI’s that work and fail for an everyday thing such as looking at the weather radar.
Bad UI:

They know my location, why make it hard for me to find?
Good UI:

Weatherbug on the iPad simple puts a stick pin in my location so it is simple for me to find my location at a glance.
A simple visual cue makes for a wonderful experience.
