Has anything changed in their design since Zach Herbert from Foundation wrote a blog post about his perceived flaws in Bitkey's design? Did Bitkey ever respond to these concerns? My personal opinion is that the advantages of Bitkey still outweigh the disadvantages, but that's maybe because of personal laziness and desire for peace of mind in not losing my keys for my current hardware wallet. I'll be curious to get feedback from the first users once they receive their pre-order. I'm still on the fence about buying it as it ain't that cheap.
