Love the design and have also wanted a super low profile mechanical keyboard like this! I have one question though - what is the travel or activation distance of the keys?
The one thing I actually like about the magic keyboard or Microsoft's designer keyboard is that the "click" is immediate and the entirety travel distance of the key is the activation bump. I dislike any amount of the "extra" travel distance (I'm not sure if I'm using the right words/description, but I hope you get what I mean) of regular mechanical switches and is the main thing that turns me off from them.
Oh also, is it possible to get a Windows version or switch the keys around to accommodate Windows as well?
The travel distance on the Altar II switches is 1.8mm, so about 0.8mm more than on a MacBook keyboard. Similar to those keyboards, there is very little pre-travel on Altar II keys.
With regard to Windows keys that is a possibility. We shipped our previous keyboard, Altar I, with both Mac and Windows markings on the keys.
What you are referring to is called the pre-travel distance. There are mechanical key options with very short pre-travel, such as the Cherry MX and Kailh Silver switches. They're mainly used for gaming.
