Mac OS X 10.1 actually made Mac OS X usable.
10.2 sort of wiped away all of the lingering bad ideas from 10.1, and 10.3 was the first release to score highly in both the compulsory and the freestyle portions of the competition.
But with 10.4 — called Tiger — Apple’s acting like a bunch of jerks about how much better they are at these things than anybody else.
I mean, they’re really rubbing Windows’ nose in it with this one. Which is hardly sporting, but it’s undeniably Good News for users.
