Fastest selling of fewer copies?

I mean seriously. Can you work out the issue with what you put just there?
XP still has a higher market share.
Start: You can still see it however, meaning that it feels less disjointed. If the modern start screen just went over the top of what is shown onscreen it would not be as bad. And what maze? It's sorted by program name or the program group with the name YOU would have set up for it.
Metro: Actually you can pin quite a lot of apps on the older start menu. The search maybe a little better (but how hard would it have been for MS to tweak the search and leave the Start Menu? That's not a Start Screen advantage, that's a tweaked search function advantage, which is different) and I always found it easy to navigate to non-pinned programs in the old Start menu.
Stop spouting tripe. I am sure MS will leave the option for either interface, so I'm not sure why you are bleating on about your beloved Start Screen, unless MS have announced they are removing that too?
