Just started using my new KBP v60 Matias Quiet Click. I think I will require some time with this one. It certainly doesn't have the same (pleasant) "box of legos" feel as my Matias Mini Tactile Click keyboard, but I like the crispness.
I opted for ESC as the bare-press for the upper left. I am sort of conflicted on that. ESC comes up so often, especially with VIM use, but in Linux I type ~ a lot also, which is kind of a vulcan nerve pinch now; I put Fn in the Caps Lock position. I will have to learn to use both Fn keys to get the most out of the layout I think.
Nice little keyboard, I certainly like it as much as my HHKB Lite. We'll see if these Matias quiet loosen up a little and let their tactile bump express itself itself.
