A New browser called Spartan to come onto Windows 10 PC and Phone with IE

With IE being the most popular and used browser of all time, Microsoft is developing a new browser code named the "Spartan" says the reports of Mary Jo Foley at ZDNet. It is expected to have a flat design like the contemporary browsers like Chrome and Firefox. Spartan would still run on Microsoft's Chakra Javascript engine and Trident rendering engine.

So, that's it until the Microsoft event on January 21 2015 where Microsoft is expected to release newer builds and a possible WindowsPhone preview build later.
