After years of hype, the Magic Leap One is finally available for purchase…at least, for those developers lucky enough to live in certain parts of the US. They are limiting purchasing for now to certain geographic areas (you have to enter your ZIP to see if you are in a lucky area). The headsets start at $2295, so they aren’t cheap, but given the promise of AR and the hype behind Magic Leap, I think they are worth looking at for libraries that are getting into AR.
Check their “experiences” page to get a better idea of the sort of craziness that is coming with AR.
