Hmmm. I was hoping for a more comprehensive review.
Codec support? Does it support AV1? VP9? etc. Does it support DSC when using DP Alt mode over TB/USB C? Essential for connecting say 1x 120Hz 2160p 10bit HDR Monitor.
It's been reported in many places that there are issues with the M1 Macs;
Bluetooth random disconnects,
WiFi 6 performance is not as good as Intel's WiFi 6 implementation,
USB 3.2 Gen 2 SSD plugged into the type C ports runs at 5Gbps etc.
When will Apple introduce Thunderbolt 4? (it's almost there), HDMI 2.1, DP 2.0 etc.
