Show HN: I spent 2 years designing a mechanical Magic Keyboard

📝 Discussion Summary (Click to expand)

Prevalent Themes

1. Praise for the design and website

"Wow, beautiful. Both the site and the keyboard. I put a deposit down." – johng
"Thank you so much! ... Glad you like the website too, I put a lot of effort into it." – aemerson_
"This looks wonderful." – sssilver

2. Desire for a fingerprint/Touch ID sensor

"I’m assuming it’s not possible for it to include a fingerprint sensor?" – charrondev
"Unfortunately not possible, at least not securely... we could include a fingerprint sensor, but it would never be able to work with things like Apple Pay." – aemerson_
"Love this. I would love to see a fingerprint sensor... it’s a deal‑breaker for me." – splittydev

3. Ergonomic and layout requests (split, numpad, tilt, blank caps)

"Great work! Have you, or do you intend to, write about the process...?" – swingboy (numbers critique)
"I would love to see this in split keyboard format... there are hardly any good split mechanical wireless keyboards." – markbao
"Would be neat if in the future the M‑Dial slot could be used for a fingerprint reader or something else. Swappable items in that slot." – johng
"I would prefer a bigger wireless box as well." – cafebeen

4. Price and manufacturing feasibility concerns

"The price seems quite low for what you get... I hope you can make a profit after everything is said and done at that price!" – johng
"Unfortunately not possible... We have delayed announcing Altar II for a long time because we wanted to be absolutely certain it was manufacturable..." – aemerson_
"I am sure there are afficionados... $349 for a keyboard is crazy. I am not sure what you get in return for such a price.." – bsoles
"We have spent a lot of time and effort finding manufacturing partners... the final retail price is $349. the $249 price is for early pre‑orders only." – aemerson_
