Oh dear. We've had this question before !
Its simple.
Windows10 is not yet released. It is still in beta.
Thus you should not be using it for real-life day-to-day applications.
Thus it is not possible (or advisable) to form an opinion on new software when it is in a beta state, because everything and anything is subject to change.
Wait until its released before you start thinking about using it or trying to get opinions on it.
