I've been on a mac for about a year, so by no means a guru. But it does have a lot of built in features that make my life easier, and having linux available as well as the ability to run windowsXP/Vista in virtual boxes integrated with MacOS has been amazing. The sheer number of tools and options available is staggering.

So a few things to get used to:

Multitouch touch pad.. I miss my right click, so you can turn it on in the system preferences for the touchpad. Tap the pad with two fingers and you get a right click menu. Added bonus it annoys the **** out of regular Mac users.

Expose... the corners are nice, clear your desktop or show all your open windows with a swipe of your finger.. good stuff.

Command+space ... to open spotlight. Its what desktop search tried to copy.

If your familiar with linux then theres a lot you can already do through the terminal.

My biggest challenge has been getting used to the different keyboard shortcuts. Many are similar but use command instead of ctrl.

Heres a list for ya http://docs.info.apple.com/article.html?path=Mac/10.5/en/14044.html.

Hope that helps a bit, There are a lot of mac resources out there, a lot of open source projects and programs available
