--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
there's definitely a difference in pointer acceleration, we know about that
(it's faster on most touchpads). The question is whether it's unusable, so far
everyone got used to it quite quickly :)

that doesn't mean we don't want to address any real issues (e.g. the x230 has a
custom accel method because of the broken touchpad). so if you think there are
continuous accel issues, we can see how we can work those out.

yeah, the reason is the multi-drag feature (or whatever you want to call it).
you can lift the finger and set it back down during a drag process to keep
dragging across more than one touchpad width. that requires a timeout though
which is what you're seeing. The easiest way to avoid the timeout is to tap
again to release (Bug 90255) which is only on git master at this point though.
