I share the preference for kbps -- and it's much more widely used and
understood. But data transmission rates have always been specified using
decimal, not binary, multipliers -- so a kilobit per second is still
1000 bits per second.

The problem of using the same prefixes for two different numbering
systems, decimal and binary, was supposedly solved when the IEC and
various other bodies adopted a new set of binary-specific prefixes:
kilobinary or kibi (Ki) for 1024, megabinary or mebi (Mi) for 1,048,576,
etc. But I believe there are fewer than 1 Ki people in the entire world
who consistently use them. :-)
