Connecting people, is somewhat like the Microsoft vision of giving everyone a personal computer. And while there are people in certain parts of the 3rd world that doesn't have mobile phones, I would say Nokia did an amazing job to get a mobile phone into everyone's hands.
My dad worked for Ericsson, so I've never owned a Nokia phone, you were the "evil rivals" after all, but I bow my head to Nokia for what they did, for how many people they connected with mobile phones.
Nokia might not have been the company that profited from SmartPhones, but they were the company that created the market for SmartPhones.
If your employees would rather have your competitors product then you need to get to work rather than to forbid them to use it you need to make it so they would prefer to use their own.
Just like it's hard to make the new Facebook, it was hard to beat Nokia. Remember, back then, everyone was using Nokia 3310. It didn't just take a better product to become the thing everyone wanted to have, because everyone didn't want a mobile phone. They wanted a Nokia mobile phone.
