Microsoft's Joe Belfiore did a really thorough job yesterday of walking us through the key hubs on the shiny new Windows Phone 7 OS, but one area that was conspicuously missed out in the overview was the Marketplace. Well, let us fill in that gap of knowledge right quick with the above image of the interface. As you can see, the first thing visible when you enter the hub is a full-screen feature for individual games or applications -- this could either work as with the music hub, wherein you see the last bit of content you accessed or, less awesomely, could function as a promotional (read: advertising) spot before you get into the market proper. The Marketplace is then fragmented into its constituent elements, with apps, games, music and podcasts leading you into their respective subsections. We've grabbed an image of how the Applications section will look as well, which you can see for yourself after the break.
