We'll have to see how this looks. I wasn't impressed going from Vive to Vive Pro, still a screen-doory pixelated mess. Glorified paperweight at this point.
VR manufactures should stop with this incremental upgrade BS until they can provide something a huge leap forward in the visuals department.
It might have less problems than the Vive Pro with screendooring because the Rift S uses a LCD screen which has less problems with that but it is difficult to compare.
I do like the incremental upgrades as I'd hate to wait much longer for more inside-out tracking alternatives.
