10147 fixed so many things for me I just hope 10154 don't bring more new bugs. They just need to fix the OneDrive problem, the System process memory leak and that StartMenu that doesn't appear sometimes. After fixing those I'll use it as main OS until RTM is released.
But still many problems i have 9 pages of fixed and not fixed problems with this build but mostly problems with apps and onedrive also if u are using a laptop video and music playing will drain ur system fast?
