I have a few, and intend to add an A9Home when they become available.

I originally had a kind of ban on such machines even coming onto my
property; but when I became a local Councillor it became necessary to
have one in order to handle such files as Powerpoint presentations and
some oddball attachments (or embedded!) that residents would sometimes
send, so I relented -- but only for that reason, so that I could better
serve my constituents one way or another.

Oh, the oddball files tended to be poorly-handled standard files,
incorrectly typed or not typed at all (as on primitive filesystems the
filetype is part of the name, would you believe! -- easy to mess up)
which I could usually extract from Pluto via Zap and Attacher.

Users here -- just like everywhere else -- are 99% non-techie types and
simply haven't a clue, so anything their system can do to make it easy
to scramble something simply adds to the problems. Even one of my ward
colleagues, who has a good brain and has been on courses, has frequent
difficulties, though not to quite the same extent as most others.

I find it all entertaining; and my colleagues seem to think I am some
kind of "expert" as I so easily unravel these unreadable oddities and
other problems, but in reality it is just so easy with a more open (i.e.
files easier to get at and read) system, a little fairly basic knowledge
and genuinely useful tools like Zap, Attacher, Thump, ChangeFSI and
OmniClient/LanManFS, all of which are free/supplied.
