Put their video[1] in 0.25x slow motion and watch at 39 seconds, the 's' they write at the end of 'Restrictions', see it gets the start and end missed and the shape distorted. Then watch the filling in sketching movements at 40 seconds, the ink appearing lags by the entire length of the pen stroke...
Yet in a couple of places, it looks like it is keeping up with writing. Where they say it's the fastest, where they zoom in on his handwriting.
I want it to be paper. But ... I dunno...
I was at their office and tested reMarkable a bit. The delay is surprisingly low. If i did quick circle shapes over the display the pen would be 5-8 cm in front of the line. When writing normally i didn't feel or notice any lag at all really. The display itself is also more rugged then a kindle paperwhite, so writing gives enough resistance to feel "paper-ish". The software does a correction after writing, so ragged shapes gets smoothed out and i saw some fills being added. I'm unsure how much of this is being tested and tweaked.
What is happening is that a light grey shadow appears very fast, and then the ink "fills in" fluidly until achieving its final dark grey. The effect is like some "magic ink" that dries in contact with air. It's not exactly like pen and paper, but they've achieved an effect that psychologically works well for me.
The Sony epad [1] seems to be right there in terms of writing speed, if we can trust either video.
You should try the Apple Pencil. Reviews, comparisons and anecdotes put it considerably ahead of the Surface in accuracy, latency, parallax, pressure sensitivity and tilt detection:

Surface Pro 4: Fails on the lowest pressure. No tilt detection at all? No wide color gamut. Bulkier device and potentially noisy/clogged fans?
I also remember seeing/reading that the Surface Studio screen "ripples" under strong pressure.

On the iPad, in some apps like Procreate, you can even control effects like the direction of motion blur by tilting the Apple Pencil around (rotating its back end in the air) while keeping the nib on a focal point.
You could also use the iPad + Pencil as a drawing tablet for native Mac or Windows apps:
P.S. Wait till Apple's March event if you're planning to get a new tablet.
Laggy as hell to the point they're unusable to me.
And as a user, I literally don't care why it's broken, only that it's broken and I have no need for a broken experience.
Really? In the history of computing? IMHO, nothing today comes close to the styluses (styli?) of the palm devices or even the casio pocket viewers. It's a pity that the industry moved ahead and these companies failed to keep up. The technology as well as the UI/Ux of the palm devices were way ahead of their time.
I don't think the silicon valley today understands that everything must be UI/UX oriented. If your UI/UX is broken, I don't care what your product does, I don't care how much it can improve my life, I don't care what you're telling yourselves or your investors: your product is broken and unusable to most of your customers, to every customer who isn't willing to put up with the brokenness.
As a customer, I don't need you, you need me.
Is there a place that shows which tablet(s) have the higher resolution, low latency styluses?
Also, they need to get the device price down. Anything over $200, and they already priced themselves out of the market for cheap tablet that has limited use.
