And there are quite a few teams at Y! working on meaningful and innovative projects. I work on one that I'd personally consider is both of those.
Giving them smartphones that are used by their majority of their users and employees will understand the pain points felt by them.
And what will happen in the good teams is that they will work it out amongst themselves. And maybe they'll get them in proportion to the market, or maybe they will swap phones every month, or maybe they will come up with other good ideas. But if they don't feel in control they are far less likely to act as though they are.
