I don't know where you are at, (Your tag line says 'Aus', so I'm
guessing Australia), but in the US, UK, etc. (ie: where most of the PCs
are), 386s are well under 1%.  Very very well under 1%.  Especially
considering you can upgrade that old 386 to a 486 and get 2-3 times the
performance for just $40-$50.  Most people long ago upgraded.
486's are in second place, losing ground to the Pentium class systems.
586+ computers are well over 60%, with 486-586 covering at least 95%.
