As we are discussing layouts, I would like to point to a bigger problem (in my opinion) with keyboards: they don't have enough keys. Let me explain. While Latin alphabet has only 26 letters, many languages have more of them. For example, Russian alphabet has 33 letters. Therefore, to fit these letters there must be 7 more keys. But we also need two keys to switch layouts - so in total there should be 9 extra keys. Sadly, manufacturers (including Apple that claims to "think different", but in this case thinks exactly the same as PC vendors) don't want to add even a single key, instead they put extra letters onto keys with symbols, so you have to switch layouts to type those symbols. Furthermore, several characters like period or comma are located on different keys in different layouts. Guess, how easy it becomes to make a mistake. Switching layouts is inconvenient. Instead of having two dedicated keys for switching to each language, OS vendors add single switching combination like Shift + Alt (Windows) or Cmd + Space (Mac). Also, on keyboard itself there is no indication that these keys can switch layout. One could argue that it is difficult to find more space on laptops. Well, I think that this can be solved somehow. For example, one could add an extra row. But it is absolutely possible on desktop PC keyboards, and yet nobody is doing this.
