Not gonna lie, actually pretty excited about this. I always hit space right below the B and N keys, always with my right thumb. This layout will allow me to reclaim some of that wasted space. It's got dedicated arrow keys, which means I can use it in Visual Studio without it being all awkward like the HHKB.
And, of course.. it's a Filco.
+1 here. I'm kind of liking the layout for a compact. You can swap BS with Backslash. A Fn 'and' Win key on the left. Dedicated arrow keys.
I like the idea of a shorter Spacebar, even on a full-size board anyway. Since I Alt with my thumbs, it would eliminate reaching so far under my palms. However, this one might be a tad too short. My left thumb typically hits under the right corner of 'V', which is in the 'taint' area left of Spacebar. But that might be such a big deal to adjust for.
All these new compact boards makes me wonder if there are plans to update the HHKB layout. The current layout has been out for years. And with everybody else coming out with improvements to the compact layout, HHKB has to be considering it.
Things I think could be improved on my HHKB...
* Fn and Win key left of Spacebar.
* Reconsider the arrow key placement.
* Possibly reduce size of Spacebar.
* Utilize the dead space in the lower corners with some much needed keys. I for one would like to have a R Control key.
