This indeed is coming. I am sure. But for now, lets enjoy some concept/mockups
Chrome on Windows Phone
These concept design images are from Yanko Andreev of 1800PocketPC. “This is my concept for alternative browser for Windows Phone. Currently The Windows Phone Software Development Kit (SDK) does not allow sufficient access to the lower level code required to create their own browsers, while in the next version it may well be possible. This will allow third party developers to port and develop apps (such as browsers) to Windows Phone much easier” he writes.
This mockup is a result of good research for sure. Here is an example “One of the basic metro (Modern UI) ideas is about the interface and the content. When you open the site you see only the content. Tabs are hidden when scrolling down. To show them back, just slide the screen up. There is option to stay always on too.”
