It is not precise when you are trying to moving it a little bit(it is likely the avoid shacking finger function are refusing it to move), but I am not sure did it is improved with Windows 10(will upgrade that laptop next year) or not.
Anyways, it seen like that Acer laptop did a good jobs focusing on just using MS driver, which avoid a lot of bug, and also has a good update experience.(as it is updated with Windows Update)
---Edit
Tried a few more times, yup, the cursor don't move for a small distance, it will only move after like 0.2-0.3 cm.
The moving distance is also improved, which is based on the dots(resolution) of the touchpad, which traditional touchpad is normally half of the resolution, not sure why.
(maybe they want to improve the movement of moving the cursor, but it feel bad when you has a 768p resolution and you can only move half of the screen...)
Just the bad thing is, you can't have a middle click or other custom functions on your touchpad anymore...
But average user don't know how to setup this, so it is not a bad thing.
Anyways, will continue after Windows 10+Office 2015 upgrade.
