bedrock

An opinion article at APCMag: "The focus of Snow Leopard is on core upgrades, not shiny new features. A bedrock focused update that delivers a streamlined, enhanced OS X.

Stability. Efficiency. A "new generation of core technologies." All this is about raising the floor on the entire system.

Multi-core optimization, support for 16TB RAM (yes, Terabytes), and a language to allow developers to tap the power of the graphics processor are just a few of the key upgrades.

But you can't lift the floor and let people walk around where the floor used to be all at the same time.
