The desktop runs roughly 6 am to 8 pm. That's Win 8.1 though.
Windows 10 Preview is on a Lenovo Laptop running maybe a few hours a day. Since updating to build 10061 I haven't noticed any problems at all.
I'm still trying to fathom Microsoft's game plan with Windows 10. It has never made sense to me to have a "one size fits all" operating system designed for both Desktop/Laptop and SmartPhone/Mobile.
1. I know there is a strong body of opinion who passionately believe the "Desktop is dead, long live the Tablet".
They need to take a cold shower and speak to IT people in government, commerce and industry. Nobody with an eye on OHS is ever going to reduce screen and keyboard sizes purely for fashion in the work place - that is where the big Microsoft $$$$ are.
Therefore it makes sense to me to have at least two versions. I'm open to correction, but I also can't see swipe screens becoming predominant over a mouse in the work place any time soon.
2. Why also
alienate volunteers who test Windows 10 Preview by emphatically telling those volunteers:
"I am afraid to inform you that in Windows 10 Technical Preview there is no option to uninstall/remove OneDrive."
Followed up with:
"This is how it has been made, in Windows 10 Technical Preview build 9926 many changes has been made in OneDrive.
You can follow the instruction given under the section New ways to use OneDrive: of the link given..."
In other words, you are stuck with it - suck it up - yes it will nag you indefinitely until you learn to embrace and love OneDrive.
3. Then we have Project Spartan aka "Edge" which gives me the impression of just being a clone of Chrome.
Yes I know they are developing for a consumer market who need never to have enquiring minds or look under the hood.
