In addition to the OS, it’s also really hard to exaggerate just how well the Apple Watch integrates into Apple’s larger ecosystem. According to many users, the Apple Watch feels much more like an extension of their iPhone rather than a standalone device. For a device that’s really an accessory to a smartphone, that bodes well.
But with Apple products, it doesn’t end there. If you also have a MacBook, you can unlock your computer or approve security requests without typing in a password or authenticating with a fingerprint. watchOS also integrates incredibly well with Apple Music, Siri and Apple’s other software features.
