Oh my god there it not??
I never thought there would be, there are many programs/apps that people already use on their computers, that could be used on a tablet, and the most important things that I think most have missed the fact that if you look at (iTunes) there are a lot of games, and most important of a lot of copies of JUNK! For the most part myself included is that people use their computer for work, not play and yes the people I know and work for are in the age group of 45+, so they are not into all the social craziness that the younger crowd is into (other than to stay on top of the kids), also they do not like change, and this is going to play a big part into people getting windows 8, and also the apps needed for it. So do not worry about a number worry about quality!
