Maybe not from a RipOmeter viewpoint but definitely ...feels different AND sounds different.[/URL]
I should mention that this WILL become apparent after the DoubleShot group buy of Signatures keys as well. Signatures are thinner/lighter than the Filco/Das.
And the Metal ones MAY have some inertial effects. Feels just a bit "deader" to me.
Is it Xmas yet?
Indeed good observations, and I agree that "deader" is a good way to describe the heavier metal keys. Perhaps more appropriate than clunkier compared to clacky, clicky, and thocky. hahaa =P
Hey clickclack, lovely keys 
Correct me if I'm wrong but I think the first 'ice' caps you posted were, err, icier? As in foggier
I like the foggier style better personally but sans skull like the new ones.
Thanks =)
Inded the first ones were a tiny bit more "frosted" because they had a slightly more rough texture. But after feedback and test runs people seem to prefer the smoother ones for the feeling and to discern the switch type underneath more easily while still looking icy/frosted. So that is what I will probably go with initially. But if you look closely at those original skull ice keys they are mostly more frosted looking because of the textured skull on top. Another thing worth noting is that after I received the feedback on the original blank ice keys (more frosted) people also thought they looked more sandblasted then frosty/icy because the surface was more uniform on a blank key.
I however personally think that in person the new ones look a little bit more like ice, especially under varied lighting and they still look and feel refreshing I promise =D
I hope that wasn't too confusing, I kinda lost my place there a few times =S
haahaa
TITANIUM!!! start carving me a full keyboard outa it. I love the stuff more than a ricer loves Carbon Fiber
My wedding ring is Ti.
Could you do a full set with laser or blasted letters on them? How much we looking for a set?
Oh. And zippy has made some prototypes you could "show 'omage too"
The first is English with some parts left out.
The second is odd Chinese, old and formal. The back space is actually a Taiwanese phrase for "to go back"
And the last is Norwegian runes. I guess summoning Thor is more important than writing LotR IV.
Zippy keys
I too have quite the love for titanium it has always fascinated me =)
"more than a ricer loves carbon fiber"? I dunno thats some devotion right there! I have been working on a new Ti ring for myself for a while now but it has taken a backseat to making keys atm =P
I could indeed do a full set in Ti with legends even, but I am still working on a way to make it affordable to non-billionaires. =S
I know how much it would cost to get setup and do 1 or 2 initial one off runs, but I don't think many could afford it.
With regards to that link you provided, I don't know exactly who I would pay "homage" to. Did someone make keycaps in that thread? I see a couple of keyboards where someone had some keys laser etched, is that what you mean? Sorry if I missunderstood, google translate can be a fickle *****.
