Yesterday I installed the 9860 build. While the tech news sites are claiming the process takes 15-30 minutes, my test laptop (an i5-3210M) took 55 minutes from the time I started the Installation, with several reboots along the way.
Visually, the biggest difference is the animations when opening or closing a window. I do like this, it adds a bit of panache to the Windows experience.
On the other hand, Microsoft seems to be slowly migrating its administrative/customization options from Control Panel to the new "PC Settings" Metro-inspired menu, as reported by Neowin:
We know the company is asking users how they could improve the new PC Settings pane, and more importantly, what it will take for them to move away from Control Panel. We can start to see evidence of their efforts on this front in the new 9860 build where you can find a zPC Settings app. The zApps naming and panel is clearly a work-in-progress carried over from internal testing used by Microsoft.
Honestly, I don't see the need to fix what isn't broken. This move suggests to me that this is the overall "look and feel" that Microsoft wants Windows eventually to take. With all that dead empty screen space, I suggest buying stock in mouse manufacturers as a lot of mouse wheels are going to wear out prematurely from all the additional scrolling that's going to be needed.
When complete, the PC Settings menu had better include every single option that now exists in Control Panel.
