Even though February 29th happens once every four years, but February 29th, 2016 will stay in memory as a very important day for Virtual and Mixed Reality. First, HTC launched pre-orders for its Vive Virtual Reality system, then Microsoft launched pre-orders for its Augmented Reality system, HoloLens. Naturally, there is a big difference between the two – HTC Vive will retail for anywhere between $799 (United States) to €899 (European Union), while Microsoft is starting to sell HoloLens Development Edition. This is far from a retail product, and just like Google Glass of yesteryear, Microsoft is pushing all the cost down to developers, and probably not loosing any money
