Nice boring rectangle, one color. I like it the crisp edges (hopefully not Tofu sharp?) and the thin bezels. I'll be keeping an eye on this for when the prototype arrives.
What is the typing angle?
Will you be releasing the plate file eventually? I'm not a big fan of brass and I know many others aren't either.
Edit: and Stripe? No buyer protection, no thanks.
And I do have to complain about your wording here:
This is a tenkeyless design, inspired by the desire to create something different. I've made several revisions on this exact design, and while I look up to many many creators, I want to pioneer something new and exciting.
Right now Infinitum looks like "more of the same, but executed well". Which is totally fine by me -- I think we need more well-designed boring rectangles, and that's personally what I want in a keyboard. But I'm just not seeing the "different" or "new and exciting" here.
That said, the Sofia is also explicitly meant to look like the Corsa. And the Mech27 very clearly emulates its side profile. Looking like a Corsa isn't a bad thing. It's just not a
new thing.
