now it's the same price of any itx board. with the same high power profile.
for the last 4 years anyone could spend $40 on a itx board with 12v power input, plus $40 for a fully featured ia64 AMD5350 APU, and have exactly what you describe for 35W (or 55 under load)
I wouldn't normally comment on something like this, but I noticed this mistake twice in the linked post as well. ia64 refers to Itanium, while amd64/x86-64/x64 refer to the 64-bit version of x86.
Now, in the x86 space both of those things (software support, reliability) are not an issue. Besides, there are much cheaper options available on the market (e.g. https://s.click.aliexpress.com/e/cSJOvljS , same platform with 4GB ddr4, 64gb emmc, case, power supply for ~$140 shipping included).
So I reckon you're right, this product won't be too successful.
