FWIW - On the last Thinkpad I bought (the X220) the touchpad was notably worse under than Windows with the official vendor drivers compared with Linux using whatever came out of the box. Two finger scrolling comes to mind - on Linux it worked smoothly, but with Windows, there was a considerable lag between me scrolling on the touchpad, and scrolling actually happening in the application.
I've noticed the same thing with my T530. The Windows drivers for the Thinkpad also don't let you set the middle trackpoint button to middle-click. There was a way to get it to work by editing the registry, but that's stopped working in recent versions too. I don't understand why Lenovo keeps putting out user-hostile driver updates for Windows. I don't see how it benefits Lenovo, so I guess it's just total incompetence.
And yeah, just like you, I find the default behavior under both Fedora and Ubuntu to be perfect.
