Microsoft unveiled the second iteration of HoloLens on Sunday (24 February), promising its new mixed reality headset would be more comfortable, immersive and useful than its predecessor. It’s also more expensive; the $3,500 pricetag is $500 more than developers currently pay for HoloLens.

For the extra cash, buyers can expect a field of view which is more than double the size of the first device. “This is the equivalent of moving from a 720P television to a 2K television for each of your eyes,” HoloLens chief Alex Kipman told reporters. “These are the smallest and most power-efficient 2K displays in existence.”
