When using it with the Mac Pro, there's no latency whatsoever, and commands are executed very smoothly.
Good to hear. Though I'm also using it on a MacPro with the above-mentioned latency present.
One case where TrackPad has a known delay is if you have one-finger dragging enabled (which is lovely), then tap-to-click (which is also lovely) if enabled is delayed slightly - about 0.3 seconds by my estimate.
Correct also. Just checked my preferences though, and dragging is disabled, meaning that I have to actually 'press' the trackpad to drag, but the latency is still present. However, oddly enough, "Tap To Click" was also disabled, but the tapping was clearly working. Enabling and disabling it seemed to reset it. Very odd!
I love technology; it complicates my life...
