Microsoft's new Spartan' web browser

Microsoft's 'Spartan' browser is shaping up, leaks show - CNET:

"Spartan, which will use the Trident rendering engine and the Chakra JavaScript engine that are part of Internet Explorer, is not just another new IE release, sources told me last week. It is expected to look and work more like lightweight browsers such as Google's Chrome and Mozilla's Firefox, sources have said. It allegedly will support extensions, unlike IE.

This week, a BGR report claimed Spartan will be integrated with Microsoft's Cortana personal digital assistant technology."
