Pictures first (sorry rainy day).
And an unnecessary video
(go to youtube for HD)
I was lucky enough to be able to catch one of these http://duck0113.tistory.com/39 . I got it mainly because the PCB was ALPS compatible and I desperately wanted to try Matias' clicky switches (but the kit includes a MX plate).The keycaps come from a SGI granite.
The build quality of the case is top notch. That baby is heavy! I'd say the keyboard ends up in the 2/3kg range. Anodization is perfect and CNC job very accurate. Also very nice rubber feet that anchor the keyboard to the desk. No way to move it once it is in place.
First disappointment comes from the switches. They are "okay" but the sound they make is very boring and the feedback not rewarding.
The sound is acute, high pitched, clanky and the click does not have a distinct character. You can't really say if the sound comes from the switch or from the cap bottoming down.
On the bright side the weight is just perfect for my fingers. Strong enough not to be mushy, light enough not to be tiring. There's one thing that I like and that is the fact the "click" corresponds exactly to the activation point. Seems crazy, but this is not always the case with other clicky switches.
I can't say I hate these switches, but they are not my preferred at all.
Regarding the layout. 60% keyboards are great as a general purpose driver. Web, email, even gaming and light coding. But when it comes to heavy document navigation and coding the lack of a dedicated arrow cluster becomes relevant.
By default (but can be reprogrammed) the win keys are the FNs. To skip 1 word right/left you need a combination of 3 keys (ctrl+fn+' or ; ), if you also want to select the word you need 4 keys forcing your hand in a very unnatural position. Also page up/down and home/end are very hard to find (even though I guess it's just a matter of getting used to it).
But this is a problem of all 60% emphasized by the fact the ALPS keycaps drastically reduce your layout choices.
That being said, the keyboard is very solid and a pleasure to look at. It's really a little piece of art and I can't rate it less than A+. The only complains I have are related to the switches and more broadly to the 60% layout for heavy coding (both very subjective topics).
As I said, like yourself, I was skeptical about the gain in productivity in the beginning and maybe I'm not more productive at all. But after about 10 months of Vi-style text editing using the arrow keys to navigate around in any text just feels plain wrong. For me using a Vi-style editor simply feels satisfying even if I'm still far from mastering Vim. "Practical Vim" (
Yeah, I know. When I first registered on a forum in 2005 I intentionally picked a name which would somewhat irritate people and which is not associated with any of my interests as I hardly listen to this kind of pop music in general and certainly not to the output of Mrs. Spears. And I don't think she's "hot" in any way. It is just a weird sense of humor. 
but I have to find ALPS blue first because these matias are boring.
