To say I'm annoyed would be very much overstating it, just a (very minor) eye-roll at one small line in a generally very good article. Just the bit quoted:
currency symbols other than the $ (kind of tells you who invented computers, doesn’t it?)
So they could also be attributing it to some other country that uses $
for their currency, which is a few, but it seems most likely to be suggesting USD.
I use it as my only personal (i.e. not work or shared) machine, and it is absolutely great. I expected to be installing a 'proper' linux distro on an external drive for the docked use-case, and it has turned out to be completely unnecessary. For those things not available as flatpak, distrobox/podman has been great. (The only thing that slightly irks me that is missing is support for a printing service, but I haven't tried that hard to fiddle with that, since I can do it from my phone on those rare occasions I need to.)
