I'd hope they take more influence from the write-up, however. I like that they'll allow Windowed apps, but their current implementation now looks like they crammed together Metro and Windows 7 without any polish. The write-up, however, has a nice cohesive experience. Of course, Microsoft's startup menu is probably early alpha, so it's a moot point.
This is definitely better. One subtle thing that it takes into account that's different from the Microsoft screenshot is that the current Microsoft version has two shortcuts for the Start Menu - the pinned start items separated by a line and the live tiles.
Jay put the live tiles where the items are currently separated by the line to make that cohesive experience. I really hope they move forward with that design for the next update.
