You need an iPhone to set up a cellular Apple Watch Series 4. After that, you can leave the phone at home and:

- Send and receive phone calls and messages

- Navigate using turn by turn directions

- Use Siri

- listen to synced music playlists with bluetooth headphones

- track activity and heart rate

- look at pictures

This is not that different from an iPhone prior to iOS 5, when you needed a computer to set up and update an iPhone.

Is the Apple Watch innovative? I would argue yes, it’s an incredible piece of technology. Will it be as successful as the iPhone? I would guess, probably not.

The phone started as an extension of the computer (iTunes was required for backup, app purchases, and syncing). The Watch is following that progression, iterating toward a stand-alone device.

I don't deny the Watch is a good product. And those who point out that you needed a Mac to use an iPod or an iPhone are correct. But the functionality of the devices themselves didn't overlap to the extent they do with the iPhone and the Watch. It's like Apple came out with the iPhone, then for an encore said "Hey, here's a bigger iPhone you can watch movies on! And here's one you can wear on your wrist!" I just don't see the Watch being on the same level as the Mac, iPod, or iPhone in terms of innovation (regardless of market success). I understand reasonable minds can differ.

There aren’t any thats my point. Its like they made the first ever car 10 years ago after lifetimes of horse carriages and you’re disappointed theres nothing else of that magnitude yet.
