We can draw attention to interesting bits, like this page: http://www.templeos.org/Wb/Accts/TS/Wb2/TempleOS.html
Reading the usesthis page, I was intrigued by the fact the author uses Windows. Actually he tweeted about switching to Linux a few days ago: https://twitter.com/TempleOS/status/461423615582298112
I find also interesting that someone writing an OS is prevented running it natively by Secure-Boot.
