Where's GNU/Linux Usage Headed?

Though projections have no real bearing on what actually turns out to be the numbers, they are fun :). The final projections from the two plots would seem to be a bit different to the naked eye. So, is GNU/Linx usage asymptotically headed towards, say 'all users' (first plot), or 'half a billion users' (second plot)?"
