OP here. For reasons I do not understand, HN seems to have re-titled my submission.

The original title is: « Why Wait For Apple? Try Out The Original ARM Desktop Experience Today With A Raspberry Pi

Future MacBooks and iMacs are going to be powered using a ARM-based chip, but the Acorn Archimedes was the first desktop to use this architecture » I very slightly edited the 1st line to fit, abbreviating "Raspberry Pi".
