This feature in Pokemon Go is one of the best ones yet. I mean, think about it: you can choose a Pokemon to be your buddy, and they will "walk" with you, and help you earn candies for their species! I am very excited for the future of the game. And by the way: I managed to get the game to actually run on my iPhone 4s. it surprises me that it actually runs, even at all. Sure, it crashes a lot, and I have it on a deactivated iPhone, but it actually works, even though it is not supposed to be a supported phone!
