Not a very convincing argument since Commodore Amigas manage to get 880K
on a normal, DSDD 3.5" floppy using a standard, fixed-speed drive.  Macs are
stuck with variable speed drives (or expensive, dual-mode ones) because they
must maintain compatibility with old Mac "standards," not because there's
any technical advantage to them.
