I agree with some of his points, but I don't think they are design flaws. Firstly, the micro-switch buttons-- I fully expected those to be uncomfortable when I first saw the design concept. Using them as a space bar would really only be useful for programming without spaces. The function keys are also not important to me, so I plan to re-map them as additional space bars (fixing the issue of a narrow space bar). As for the display, it does look pretty ugly, but I don't this is a problem for a first product with other priorities. As for why it's there at all, I don't think its utility will be limited to displaying the key mapping; that's sort of the point, to make this keyboard hackable. I think it was a good decision to omit the escape key-- it's just not that common to use because it's difficult to reach. I'm not as familiar with Vi as I would like to be, but I would probably re-map escape even if there were an escape key. This keyboard definitely won't lack modifier options. Arrow keys suffer from the same problem, and any logical layout wastes space. As for home, end, page up, page down, etc... The placement of these keys is so variable between keyboards these days that I feel like some people would be unhappy with any placement. I probably would have preferred a more full keyboard layout, but I really don't think it's necessary given this level of flexibility, and spacing everything out like that is inefficient.
All that said, I do think some of these problems should be solved with time. For example, offering long key-caps to span the mod/space and fn switches. Offering a more cushioned hand rest would be nice if it's easy, but I would much rather let them focus on developing core functionality.
I for one am very excited about this. Loud, directionless, and without escape is exactly how I prefer my keyboards. It is unfortunate that the modules aren't ambidextrous, but I hardly use a mouse anyway and I'm right-handed. Rather than fixing that, I hope they start working on Bluetooth modules next. Maybe some battery modules and get this baby working on my phone.

On the topic of accessories, I just found this: https://www.reddit.com/r/MechanicalKeyboards/wiki/numpads
Modular is always better.
