It is clear that the experience on a VR device is much more impressive than on a mobile but we have to accept the reality of the numbers. It will take many years for the number of VR glasses to approach the number of mobile devices.
Even now there are only 20 million VR headsets (growing at 30%) compared to 15.000 million mobiles and tablets (growing at 5%).
If we have to choose a market for a #metaverse project for the next 5 years, compatibility with mobile devices is clearly a must.
