I spend a lot of time on power opt for small systems. The promises w.r.t. power numbers when taken in conjunction with promised features/brightnesses are 100% a lie given current SoC/battery/cooling tech.

"absolutely no latency" -> only apple manages anything close to this, and that -- with custom silicon that can feed data from the camera to screen while it is still being read out from the camera. A no-name startup doing this ain't happening.
