On the one hand, I understand why a "large market audience" device would
need HDMI or DisplayPort or the newest whizbang 256K DNA ("Direct Neural
Attachment") adapter is ... but why does that need to be on a
small-market / hobby computer?

I can only speak for myself, but a reasonably open PC at the $400 mark
would certainly be competitive to dell or hp; even if it were "limited"
in the peripheral interconnect area (assuming, of course, the
motherboard's peripheral layout were well documented and people were
encouraged to make stuff -- see arduino or rpi expansion boards )
