It's rather uncommon to run into a "y" in German, so why give it such a central position on the keyboard? "Z" is more common, if only because German has a "tz" digraph. Es ist eher ungewöhnlich, im Deutschen auf ein "y" zu stoßen, also warum sollte man ihm eine solche zentrale Position auf der Tastatur geben? "Z" ist üblicher, und wenn es nur wegen des "tz" Digraphen ist. Two sentences saying the same in both languages. English: 3 "y" and 0 "z" outside quotes. German: 0 "y" and 2 "z" outside quotes.
