Tiger Key Features are:

Spotlight:
Find anything on your computer instantly with Spotlight, a new desktop search engine completely integrated into Mac OS X. Spotlight quickly searches everything on your personal computer-including documents, images, movies, music, email, contacts, appointments, and system preferences-and finds what you need with pinpoint accuracy.
 
Dashboard:
The Dashboard is a new view in Mac OS X that zooms on top of your Desktop with a click of a function key and, like Exposé, disappears just as quickly and easily. Dashboard displays timely information (e.g. Stock quotes or current weather) and frequently used applications features (eg. iTunes playback control or Address Book contact look up) using small applications called widgets.
Mac OS X Tiger includes a selection of built in widgets and a rich developer environment to allow for dashboard extension.
 
Safari RSS:
Scan all the latest news, information and articles from thousands of your favorite major news organizations, community web sites and personal weblogs in one simple-to-read, searchable article list using Safari RSS. RSS (Really Simple Syndication) news feeds allow major organisations and individuals to easily publish to the web. Standard protocols make it simple for applications to access and organise these news feeds.
 
iChat AV:
Tiger iChat AV puts multi-way video and audio conferencing right on your Desktop with new video technology that delivers significantly better picture quality. Up to four people can see and hear each other in real time and up to ten people can participate in an audio conference. iChat AV in Mac OS X Tiger is powered by the new H.264 video codec in QuickTime to deliver quality images and increased resolution.
 
Quick Time 7 & H.264 video codec:
Mac OS X Tiger includes H.264 which is the next generation, industry standard video codec that is able to deliver DVD quality video at lower data rates than was previously possible. H.264 video produces a sharper image and makes background details appear clear by delivering a dramatic reduction in compression artefacts. Mac OS X leverages the power of the dual processor PowerMac to provide real time compression performance.
 
Automator:
Automator is an innovative easy to use application that automates simple, complex or repetitive tasks without requiring the user to write scripts or have advanced technical expertise. To automate tasks, users add "actions', that correspond to each step of the task, to an Automator document called a 'workflow'. Once a workflow is constructed it can be run from within the Automater application or be saved as a document executed from an Action or Script menu. Workflows can be shared with others.

· Macintosh computer with PowerPC G5, G4 or G3 processor

· At least 256MB of RAM
