Oculus and Google Glass other then being head worn displays they have something else in common

they both have camp followers who are attempting to piggy back on their notoriety and to capitalize on their shortcomings. Oculus is the King with dozens of imitators.  Shortcoming, it's obvious anybody can make a serviceable version of the Oculus with COTS components in a day or so that is in performance is indistinguishable from the original.
 Two companies now have seized on Glass's Battery problem with their own "solutions". Speaking of Elvis first to market was Glass Sideburn.

"I'm caught in a trap, I can't hold on because I love you too much baby..."
Neat huh? Now as Russians seem to always be on the ground floor if these "solutions" like the Two Crazy "Virtusphere" Russians were first with a knockoff of Oculus here we go with another Google Glass Battery "Fix" because "2 hours of usage of such a great device is not enough."
