Still, google and apple do this from day one ( Well, apple probably not from the actual day one they started) and ms only since a short while.
I suppose with the history windows versions have, people are quick to jump on the bandwagon. "
But anyway, I don't see much wrong or better in win10 compared to win 7. I still do like the new start menu, edge is not very pleasant to use, ms uploads the monthly patches to my pc no matter what setting I use.

I guess in a matter of time all will be forgotten and most will be on the win10 train, especially when dx12 games start to really take off.
As for charts showing user numbers, I tend to take those with a grain of salt, because when a product is succesfull, there is no need to produce such numbers to start with.
