I tried to buy this, when it was released. It sold out instantly. I was sad.

This looks awesome!

I would buy it instantly, if it would be a scientific calculator, ideally with RPN.

Oh and i would have used a LCD with amber on black.

Knowing about Japanese Lacquer (aka Urushi) will change the way that you see the world. Urushi is the sap of a tree that is related to poison oak and posion ivy. You can learn to use it by wearing a biohazard suit or by suffering through until you develop an immunity to the urushiol. To call it "the itch" does not do it justice. You do not really know the full depths of being a human until you decide, with full knowledge of the consequences, to go down this road.

Urushi is transformed by curing in a warm and humid environment to something that is food safe and not toxic - for example Japanese rice bowls. Then there are they myriad decorative techniques such as Rankaku - using quail egg shells for decoration.

I've recently seen the word "entanglement" in a completely different context. But Urushi entangles you in nature and your environment in way that is utterly breath taking. For example: https://www.sothebys.com/en/buy/auction/2019/modern-masters-...

This is amazing. If you've ever held a fountain pen with this finish you know.

Looks like I need to plan for a weekend trip to Tokyo to get this and along with my annual pilgrimage to Akihabara

About $600 apparently. The regular S100X is $350.

There's also a Hokusai range of calculators I saw at yodobashi camera Yokohama this spring. It was 60$,I didn't buy it but I kind of wish I did.

This is almost certainly a Japanese product for Japanese people/companies who will give it to other Japanese people as a GIFT. Japan has a never-ending gifting protocol. People buy perfectly normal beer in a fancy box, to give it as a gift. It's a nice thing about Japan that is particularly Japanese, which is probably why many of you don't understand the purpose of this product. I bet if someone gave it to you spontaneously, you'd appreciate it!
