The excitement continues to build for tomorrow’s WWDC keynote and the developer announcements that are sure to follow. Yesterday, we took a look at what to expect from iPhone OS 3.0, as well as at Apple’s strategy for rolling out updates and why they include (or, more importantly, don’t include) certain features in each iteration. Today, we’ll examine Snow Leopard, the next big update to Apple’s Macintosh operating system.

Mac OS X v10.6

The code name for this latest release of Mac OS X is Snow Leopard. The name is important not just because it’s another big cat ( like the other names they have used: Tiger, Panther, Jaguar, etc…) but that it is very similar to the code name for the current release of Mac OS X v10.5: Leopard. Snow Leopard will seem a lot like Leopard to most end users. Expect a few cosmetic changes and maybe some subtle differences, but the Snow Leopard release will be all about what’s under the hood.

When OS X was first released, it was a revolution for Macs and, in many ways, for the PC industry as a whole. It was a modern operating system that had been built on top of a proven Kernel, but was still very accessible to the average user. Once again, we see the themes of stability and security coming in to play, as most consumer operating systems were buggy, unreliable and virus-ridden. Apple released a sleek, fast, stable and secure OS that was easy to use and very powerful in what it could do. It appealed to consumers and power users alike. It was, and still is, the minority platform, but it quickly became the one to watch.

Now, with Snow Leopard, we have the 7th generation of this operating system (We started with 10.0, and not 10.1). It has come a long way since March of 2001, and has matured well over the years. However, every release has been packed full of new features to keep people buying the new OS. With Snow Leopard, Apple is taking a much needed break from new features and has spent the last year-and-a-half streamlining the OS and the apps they provide with it. This is a bold step because without a lot of new features, a large majority of their user base will not be motivated to upgrade until they buy new hardware. Certainly Apple recognizes this loss of revenue opportunites, but they’re staying true to their vision of security and stability in streamlining the OS. For this, Apple deserves our applause.

The reason this streamlining is necessary is because Apple pulled off an amazing transition a few years ago when they moved us from the PowerPC processors to today’s Intel processors. This was not an easy task, but they pulled it off very smoothly and with very few problems. To accomplish this, the OS had to make some compromises. Now that the transition is complete and far enough behind us, they can focus on building an OS that really takes advantage of this new architecture. This release will see better use of multi-core processors, more efficient memory access, and even the ability for developers to use the latent power of the graphics processors for non-graphic purposes. In short, it will be a more stable, secure and reliable OS that is easy to use and does not intimidate those who are attempting to use it.

Evolution of a revolution

Both the iPhone OS and Mac OS X were revolutionary operating systems when they first came out. They allowed us to do things that we weren’t able to do before. These two operating systems are the real jewels in Apple’s crown and the keys to their success. Millions of people have purchased, used and discussed these systems and the devices they power. They have changed the way we think about computers and mobile devices. The anticipated releases of the new systems are far more evolutionary than revolutionary, but every revolution needs to eventually mature and evolve into its full potential. We will see some new features for consumers, but I have a feeling that both platforms’ developers are very excited about this year’s WWDC because of the evolutionary changes to the revolution they first signed up for.

Welcome to the evolution.
