Hot corners allows you to designate some sort of event that should take place when you scroll your mouse into one of the four corners of your screen. For example, you can set it up so that when you place your mouse in the bottom left your computer will go to sleep. This is one of those features that is hard to live without once you get used to it. You can configure hot corners in “Expose and Spaces” under System Preferences.
Spaces almost goes hand in hand with hot corners. This feature allows you to split your desktop into multiple screens and is very useful for multitasking. It can be configured on the same screen as hot corners.

Although it has features like iPhoto, Mac doesn’t come with any advanced photography editing tools like Photoshop.

Quicklook is one of those features that really sets a Mac apart. You don’t even have to open the file to read what’s inside. As unbelievable as it may seem there are some plugins out there that can make it even better.

Activity monitor in dock
By using this tool you gain similar functionality to the task manager in Windows. It is a good idea to add this item to your dock because it will take on some extra functionality. Its icon will actually display a pie chart of memory use and if you want to force quit applications it will provide you with a lot of extra information about processes you have running.
If you travel a lot or you just want to conserve your battery life you may like the fact that your Mac automatically dims the screen to save your batteries.
