Tonight I met two delightful young women at Bloomen und Planten. One was a kindergarten teacher and the other was a shop clerk. Since I do not speak German, we conversed in English and iPhone. When we could not think of the word we needed we pulled out our iPhones and found the word. iPhones are good at many things.
As an aside there are a lot of iPhones in Hamburg. I wonder if that will be the case in other cities?
