$129 is the price OS X costs ($99 to upgrade).

Wait, what? There is no "upgrade" version with a lower price. There is a student discount version for college/university students, and a volume license of 5 seats for $199 (Family Pack), but the only other one for end consumers is the standard package, which is $129.
 
I don't particularly see any reason why they might change their pricing model.

$129 for 1 license
$199 for Family Pack
 
Well, now that I think of it the $99 might not exist anymore. But I swear it did at one point.

Since when has the price not been $129? Pulling it out of my ass is a bit uncalled for if I must say so.

Don't get your panties in a bunch Iha.
 
They do have upgrade dvds, but isn't that for the interim period between announcement and shipment (and depletion of the supply of the current stock with the older OS). I never understood that to be independently for sale.

I would guess that it wouldn't make sense for Apple to have an "upgrade" OS, since every release is in effect an upgrade. Unlike PCs, you can't just build your own and dump an Windows OS in from scratch. Because you have to go the Mac route, you already have Apple's OS in your machine anyway.
