Microsoft decided that copying everything Apple does in their software a couple of years after the fact was not enough, they also felt the need to copy their store designed as well, right down to the furniture and the staff with the coloured jumpers etc.
As the Apple staff are prone to the clapping and cheering at product launches etc M$ decided to have their lot break into "random" (
) dances every now and then, but it just comes across as rather, well, tragic...
That's the saddest thing I've seen since the how to have a Windows 7 launch party vids...
