IJ Reilly said:I suppose I'm comparing them to the four major upgrades we've seen to OSX since the release of XP.
Oh, gotcha, I think that's fair. I was just answering the question of whether they ever add any functionality. I think they do, but it's not terribly significant.
I think Windows service packs tend to be somewhat more significant than the average dot upgrade for OS X (like 10.4.5 to 10.4.6), since most of those don't add functionality, but a lot less significant than the changes between major revisions of OS X, like Panther and Tiger, etc. But that's been done a few times on MR and I don't want to start that flame war again!
