As others have already noted, the MacRumors article really should be updated to note that it doesn't have a GPS chip now (contrary to what was announced back in January). It's now only "connected GPS", i.e. it needs a phone to be paired with it and nearby to get location info and can't be used for standalone workout location logging.
So no GPS, no LTE, no NFC for payments. I'm not even sure why it was posted here, it's just another basic Android Wear device with nothing particularly interesting about it. Certainly it's no competitive match in fitness tracking features to the Apple Watch S3 (or even S2).
