Cute, but for a device targeted at us "experts" (see the Pentagram design brief linked elsewhere in-thread), this feels like a missed opportunity to explore the last couple of decades of advancements in HID design that many of us have benefited from (e.g., a mouse designed off hand curvature, or a split keyboard). If you want to see computers for experts (albeit in a more restrained design space), look at Framework.

I was just about to try to grab this and try to contact them to return it, but the WHOIS records say it actually is still registered to them, and it expires in 2023. Phew! Maybe they need to update some DNS records?
