If they were looking for a business opportunity, they should have asked another question, not limit the possible answers.
A "refurbished" mac with AROS on it sounds like a possible business opportunity to me. If it´s bought from Ebay or something, apple won´t care.
But with another question, I might have answered
"go for the miniITX, fanless console/mediaplayer thing, not laptop or pda".
