Doing the math to compare resolution to the Hololens... Hololens has "2.5K radiants," where a radiant is a "light point per radian." [1] A radian is ~57.3 degrees, so 2500/57.3 = 44 pixels per degree. Meta has a "2560x1440 display with a 90 degree field of view." Horizontally, that's 2560/90 = 28.4 pixels per degree. Having used the Hololens for 30 minutes at Build last year, the field of view was definitely less than 90 degrees. However, the tracking was perfect, there was no lag, and generally speaking the illusion was complete. Watching the video at the top of metavision.com, it's hard to get a good impression-- some shots look like they pointed a video camera through the Meta glasses!? The frame rate is noticeably low and the gestures look like they... sort of work. Both headsets' problems seem fixable-- Meta will presumably fix the lag and gesture accuracy (assuming those weaknesses in the video are real). And Hololens will presumably get a larger field of view with later hardware revs. To me it'd be a mistake to dismiss these systems as not being ready. It probably won't be a long wait.
