I have a HHKB lite which I used for quite a bit before I went to the BS keyboards. I liked the small form factor alot. It made using the mouse on the right side bearable. But its rubber dome, its ok for what it is , but not ideal. You mention the layout as being key, and in a way it is. But it doesn't click, yet you say it is satisfying.
damn.
You know if I could just walk into a store and touch one, I would know in a minute if it was for me or not.
I am not much of gambler, I typically lose, but everyone here at geekhack speaks so highly of it. That alone makes me want to get one.
I know there is warehouses full of them, but they are halfway around the globe.
