Spaceman's 2 Cents:
Pros: * This particular model can talk on Zello, as well as VHF/UHF/DMR. Not all radios offer both VHR **AND ** UHF on the same unit. * 13MP Camera* Android 8.1 (which is only one version behind as of when this was written)
Cons: * It's FREAKIN' HUGE* It's FREAKIN' EXPENSIVE - currently going for right around $1100.00* Not crazy about the screen's resolution specs* No USB Type-C ?!?!?

Spaceman's 2 cents:
PROs:
This is one of the only "Network Radios" that comes with the current version of Android.
4G compatible
Battery capacity is good
You can also have VHF (137-174 MHz) *or* UHF (400-470 MHz) capability for local (non-IP) communications

CONs:
The Screen Size/Resolution, Memory and Camera is a little lacking, so I wouldn't use this as a device that will replace your main phone.

Overall: the addition of the conventional VHF or UHF capabilities makes this device worth buying in my opinion. There are other models out there that offer the same type of features, but this one seems to be the best one out there right now.

Additional Notes

There are some other Zello compatible walkie talkies out there that don't have screens. They would need pre-programming any time you would want to add a new channel.

While this may be ok for the radio guy that wants a radio experience, you're limited as you won't be able to receive texts, images, or locations from other users. So because of that, I would recommend staying away from network radios without screens.
