Microsoft’s Windows Phone 7 is on the horizon, but how well with the WP7 IE browser stack up against the likes of the iPhone 4 Safari browser and the Nexus One Android 2.2 browser, well you are about to find out.

What we have for your viewing pleasure today is a browser battle between Windows Phone 7, the iPhone 4 and the Nexus One smartphones in a video that comes out way courtesy of Rosa Golijan of Gizmodo and by way of Brandon Miniman over at Packet Now.

Brandon does stipulate though that the Windows Phone 7 hardware and software in the video comparison is not final as the software is still a work in progress while the hardware is not meant to be released, and thus this comparison is purely for fun.

He does say that with Windows Phone 7, the tab management is “super quick” and website loading is competitive while panning/scrolling/zooming are “ultra-smooth.” So rather than me tell you about it why not head on down below, mash that play button and check out the battle of the browsers for yourself…enjoy.
