I don't really consider that to be the early adopter phase of OSX. If you go by the whole technological lifecycle theory that'd be the innovator phase (though realistically I think it was mostly just the most die-hard left of the old guard Apple fanatics).

To me it's when the Intel macs came along (10.4.4 I think) that new adopters really started picking up steam, but the ecosystem they helped build wasn't really there yet.

At least, that's my perception.
