It's impossible to move the cursor slowly smoothly. It jerks around.
Here is a video.
It's kind of hard to tell whether you're being genuine or just looking to stir up a controversy - talk about your made-up "issues".
If you really think the trackpad is behaving abnormally, then take it to an Apple store (or authorized service center), or compare it to any other MB you can get your hands on. That aside, there is nothing wrong with the rMB trackpad as far as "jerkiness" goes.
First, video quality of your linked video is so low-resolution and pixelated that ANY trackpad is going to look jerky in the video (I hope you don't actually have your resolution set like that... it would explain a lot, LOL).
That being said, I think I know what you are referring to, and you apparently fall into that 2% that could possibly even notice the "jerkiness" at normal viewing distance... kind of like the folks that claim they can hear the difference between 256kbs AAC and a CD.
I have a rMB, a MBA, a nMP (with 4K 27" displays), and an original apple magic trackpad and magic mouse (both of which are practically brand new - I generally use a different mouse with my nMP), and so I just wasted 30 minutes of my life comparing them. Even trying to slow down cursor movement to the ridiculousness shown in the video, I see very similar results on all the displays with all the input devices.
I would chalk the "issue" up to problems you had in your childhood, errr j/k... seriously just in comparing my gear, the magic trackpad's glass surface feels slightly smoother than either rMB or MBA trackpads (I would never notice that without literally having a finger from each hand on each at the same time). Maybe whatever trackpad you were used to was well worn and offered less fingertip resistance.
There's also the trackpad's "Tracking speed" to consider (I usually have mine set to 4 or 5). Going out on a limb, the retina display may contribute to the "issue" as well... even using the magic trackpad with the nMP results in ever so very slightly more "jerkiness" compared to the MBA.
Of course you're entitled to feel the way you do about it - everyone's sensitive in different ways. For the other 98%, there is no issue with jerkiness of the cursor.
(FTR, personally I have an issue with the trackpad due to the cursor jumping around from inadvertent palm touching, so it's not like I think it's perfect either)
