Wow! Do you then use white board erasers, chalk board erasers, paper towels, microfiber clothes, squeegees ;P, or what do you use then to erase?

Is there a particular advantage to getting the black version of this versus the ultra white version?

In a previous apartment, I painted a wall with several coats of blackboard (chalkboard) paint and then used fancy chalk on it, and a chalkboard eraser. Worked pretty well. The landlord even let me keep it up when I moved out, because the next tenants liked it.

Slightly off topic, but if you ever write on a whiteboard with a sharpie, you can write over the text with an erasable marker and then wipe it away.

This works because the solvent base for the ink is alcohol, so a much simpler method that doesn't waste ink is to use a small spray bottle of isopropyl alcohol. Ideally 99/100%, if you can get it. (Try eBay.)
This doubles up as an effective whiteboard cleaner.

You can do the same with a Sharpie. All inks contain a solvent for their pigment, so you can use the same marker to remove the same ink. Just mark over it and immediately wipe it off.

If you want to remove Sharpie, use IPA...isopropyl alcohol...India pale ale remains useless.

Your pale ale clearly isn't strong enough!

Isopropyl removes all inks and glues. It's incredible.
It's also fantastic to wash your hands with when doing cell and tissue cultures and trying to avoid contamination.

It's also similarly great for killing braincells when auto-applied orally

No. You're thinking of ethyl alcohol. If you ingest isopropyl alcohol you're gonna have a bad day.
Oh and make sure the label on the ethyl alcohol does not contain the word "DENATURED." That's code for "tastes like shit and makes you sick."

Well, if the stated goal was to kill brain cells, I'm sure either will get you there

Even better, sunscreen (I just use old, expired ones). Don’t know why, but it does a great job.

Get a real blackboard made of slate and quality chalk. Much higher resolution than markers.

I'm glad they work for you, but out of curiosity, does anyone else find... just about everything about blackboards unappealing? The feel of chalk scratching on the board, the sound, drawing the characters (making curves feels awkward to me), even the chalk dust. I prefer whiteboards in almost every way except for markers drying out. It's one of those things I've kinda never understood why so many people prefer chalkboards.

Scratchy chalk is low-quality chalk or poor technique. Every writing instrument has its own techniques. Like how fountain pens work better at a lower angle and lower pressure, and ball-point pens work better at a higher pressure and the angle doesn’t matter so much.

Or poor quality boards. I know I didn’t use a real slate board until later in university and it makes a world of difference. Really you need both, great chalk and a great board. But when you have both the feel is superb :)
I wonder if they make a giant wall mountable version?

I have a couple boogie boards, and they're very handy for making notes or single-session scribbles, but their major drawback is the "all or nothing" reset.
I don't think I realized how often I need to erase or update a small section of a list or diagram without erasing the entire thing until using these.
What would be the fancy modern buyable version of this?

Keeping it classic, nice. How do you manage the dust?

Perhaps with multiple vacuums attached on the bezels.

White boards, or rather the markers, are barely legible.
I'm using a glass board with glass markers. Good contrast, good colors and the board lasts forever.

I recommend chalk. Its a little dusty but works great.
Seems to be nontoxic and low in the chemicals and plastic department.
Chalk. Even comes in colors.
I'm not joking.

Also it's actually gypsum. Same material plaster and plasterboard is made from.

Are you sure about that? According to Wikipedia both gypsum and calcite are used. Apparently, gypsum is used for colored chalk, and calcite is used for white chalk:
> Chalk sticks are produced in white and in various colours, especially for use with blackboards. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk or limestone, while coloured chalk sticks are made from calcium sulphate in its dihydrate form, CaSO4·2H2O, derived from gypsum.[6][7] Chalk sticks containing calcium carbonate typically contain 40–60% of CaCO3 (calcite).

The first of these seems more relevant... I'm not quite sure what the second citation adds.

Sounds like a giant Etch-a-sketch?
There are these small electric blackboards that you can push a button to reset: https://myboogieboard.com/pages/blackboard-smart

This is 55inch one
If you can do VR whiteboard it's probably the best option.
I dont understand why anyone would use chalk.
