Everybody’s favorite OS X update, Snow Leopard, is hurtling in our direction, and Amazon has either been given the go-ahead to (or just gone ahead and) opened up pre-orders. They have caveats for both date and which update package to get:

Please note: Official release date has not been announced by Apple, though they have indicated this product will be released sometime in September.

Oh well. They’re also careful to point out that the $29 version will only work on 10.5 (Leopard) machines — nice to see an intervention there to prevent any less-savvy 10.4 users from thinking they found a great deal. They also point out that it’s “the world’s most advanced operating system, finely tuned.” Okay, I know that’s Apple talking, Amazon, why’d you put it up top? Anyway, here are the links:

Snow Leopard (upgrade from 10.5) $29
10.5 upgrade 5-pack $49
Box set (full upgrade, iLife and iWork) $169
Box set 5-pack $229
Snow Leopard Server $499

We’re all pretty pumped about the update; the major new features should make OS X better than ever. With Windows 7 right around the corner, I’m thinking both my PC and my Mac are going to a little bit more awesome by the end of the year.
