This isn't a regular workstation, this is an extremely high end workstation.
Workstations for average work costs less than $1,000. Hell more on the $500-$700 price range.
Think about the costs of replacing a whole office with these. 10 of them will be $50,000 dollars, this is definitely more for an independent professional. Which is ridiculous considering the current line of mac mini and iMacs (without spec upgrades) Hardly can last more then couple years with its already out of date hardware (the hardware was out of date even the day of release for these computers)
The 1st Gen (USB-C) MacBook was so underpowered its just ridiculous, along with so many of their other products. If they just stuck with the industry standard of up to date hardware imagine how much more sales they'd make.
the 13" is still has a dual core processor. Its just ridiculous.
You're confusing the term Workstation with Desktop.
