I love it when people call VR niche. The quest 2 is estimates to have sold a similar number of units to the Xbox X and S combined, and about 3/4 the number of units as the PS5 [1]. It is now a mainstream console.
a mainstream console is used everyday. how many VR headsets are sitting unused on shelves? the volume of sales is far from being the most relevant metric.
