These look like such great keyboards, except for the fact that I cannot possibly buy a board with such fantastically hideous legends. What on earth were they thinking?!? 
Why is there nobody out there making sensible PBT keycaps? A well-designed font, sized and placed aesthetically and ergonomically, with clear symbols.
(And c'mon, would it really be so hard to make the three extra molds to make Mac keycap replacement sets? If they can do Tux, they can do Mac.)
They do, they're just rather expensive usually. Ducky makes nice PBT caps with a professional sans-serif font as well as engraved ones on the Yellow Shine 3 (the caps are quite good, I have the blank ones, though). IMSTO also makes good ones, they're just prohibitively expensive to most ($70-90 in different colors), and Vortex has a rather polarizing font, but they are double shot. I like them personally, but they are quite odd. They just made a new font which seems much more agreeable to members, though.
Do you have a link to the new Vortex font? I can't seem to find it.
As far as I know, nobody makes something that meets
all of my (admittedly very high) standards.:
- PBT
- double shot
- ideally backlit legends (à la Max Keyboards or Hassium/Francium)
- an attractive and ergonomic font (Max is grudgingly acceptable, Vortex and Deck use key legends that make me vomit into my mouth)
- flat Windows keys -- I detest the glossy dimple
- Mac keycap options (we're talking three essential key molds here. More if you include F13-15.) For non-doubleshot keys, it is baffling to me why this isn't widely available, given the small effort.
- it would be magical if someone made a truly Mac-optimized set that included all 4 characters per key (no modifier, shift, option, and option-shift), as Matias does on its Mac keyboards.
- for keyboards, a Mac-friendly layout -- specifically, the modifier keys to the right of the space bar. Many (like Max) put an Fn key in a key location

So my take on the backlit PBT candidates:
- I was really close to buying a yellow Ducky, but I am not a good enough typist to have blank (or nearly-blank, as on engraved) keys.
- The Max Blackbird puts the Fn key one away from the spacebar on the right, where the Mac's Option key belongs. (Option is a very useful key on the Mac.) Dunno if that can be remapped.
- The Francium would be good, if not for that unspeakably hideous font.
I'm assuming my best shot, realistically, is to give up backlighting and get blank white thick PBT caps and have them custom laser-etched somewhere.
Is this post so long and off-topic that I should make a separate thread?
