Please don't tell people what they should be working on. If you want
to see something happen, get to work yourself. If developers are not
participating in this discussion is because we have already shipped
products and now about all the hidden costs that you are so happily
jumping over. And of course, are busy making things happen instead of
Not saying that a great educational platform cannot be built on
Android, just that this is obviously not the moment to be considering
it when we have hundreds of thousands of people using the existing
