1. Apple Mac OS X 10.6 Snow Leopard Server
Snow Leopard Mac OS 10.6 isn't a blockbuster. It has a few new applications that aren't likely to start an Internet storm. The updates to the existing apps are the polish of this version, one that quietly fixes and augments the applications. There is no reason not to retrofit Snow Leopard into an existing Leopard-based environment. The price at $499 is reasonable ($29 if upgrading from Leopard), but made more expensive by captivity to Apple's comparatively pricey server hardware. As a plug-and-play combination, Apple's controlled Snow Leopard environment provides a seamless experience.
