Maps

Nigel Warren:

There's a common theme running through all these improvements: speed. Maps have to be accurate, yes, and by most accounts Apple has their work cut out for them in that area. But as I found out when I was testing Google Maps back in the bad old days of flip phones, speed can make or break a mapping app just as effectively as bad data, and any improvement in that area is welcome.

This applies to all user interactions. Speed — both how streamlined and interruption-free the user interface is, and how fast the application performs — can be the difference between an awesome user experience, and a horrible one.
