So... Far.

Windows 10 on the desktop? Solid. Windows 10 on a touchscreen laptop? Needs work; specifically, in tablet mode. Like, the design is sound, but it just doesn't quite work yet... Windows get lost to everything but the Task Manager, some apps have constant title bars that simply aren't there in desktop mode, and Solitaire is buggy as all hell. I really like tablet mode, but man, I wish it wasn't such an afterthought :(
