Glad the author used the Bloomberg stock finder input as an example.

I've been teaching my father in law how to use the Bloomberg app on his iPad and this was one of his biggest stumbling blocks - he just couldnt work out why the keyboard wouldn't appear.

With the adoption of these types of devices moving to include the "non-tech savvy" population, who aren't as quick to work out unclear UI, we start to see how small UI choices can have a dramatic effect on usability.
