Compromises:
1. Single speaker
2. Single camera
3. Extremely poor battery life (due to thinness)
4. Inferior C1X 5G modem compared to SD X80 in Pro series
5. Too thin to hold.
6. Busted Wifi 7 that is incapable of 320 Mhz channel width on 6Ghz.
7. No mmWave which is in Pro models.
8. No display output via USB-C to an external monitor or TV.
Did I miss anything?
Yes you missed some stuff:
- CPU throttling compared to the Pros
- Binned version of the Pro CPU
- USB 2.0 port speeds
- Overheating issues
These are fair points, but they're not going to affect the vast majority of users.
The only things you could really make an argument that most people would miss is single camera and smaller battery than the Pro models.
You could start making the same argument for MacBook Air and say it shouldn't exist as well? or iPad Air?
