Those thinking about diving into the smartwatch world must think carefully before spending a lot of dollars on an Apple Watch. If you have an android phone, you don't need to think about it, as many of the features would be rendered useless and only work when used with an iPhone. If you have an iPhone, go with the basic model, which isn't as costly as the series 7. Sometimes people don't use their Apple Watch as much, and getting a basic model would let you know how useful it is.
