Google(s goog) Glass might not be the only big name in connected eyewear if Microsoft(s msft) has anything to say about. Redmond is reportedly testing prototypes for a Google Glass competitor, according to the Wall Street Journal. Details are scarce, but I’m inclined to believe this is true. After all, Microsoft was late to the game with Windows Phone, which has cost it valuable market share. Wearable tech is becoming increasingly popular, and the only major competitor in the eyewear space right now is Google, which gives Microsoft a chance to get in on the ground floor.
