meh, ripping DVDs at the moment. I've been doing eveything on my iPhone for a while. I may get rid of the Macbook and go iMac next year.
 
Kinda-sorta work at home but I jump from one thing to another:

General:
Mac Mail
Browse (Safari)
Music (iTunes)
Chat (Adium)

Web Development:
Coda
CyberDuck
Pixelmator
ImageWell

Games:
WoW
 
Internet, Music (both listening to and creating) and college work and research mainly. Researching/studying/typing up essays is a lot nicer experience on the mac.

I don't really use it to watch DVDs or play games, although i watch stuff on the BBC iplayer from time to time. I occasionally do a bit of flash programming for my computing coursework too.

All on my Mac Mini, my only computer. Its fine for what i do, although i might get a macbook soon as I'm beginning to need the portability.
 
I use my iBook G4 for pretty much everything, it being my main computer.

-Web
-Music
-Chat
-Movies
-Light gaming

I'm currently preparing to give my old IceBook to my sister, because she wants it so much. (The thing barely works, I don't understand why she would want it at all.)
 
Seriously, everything. It's a wonderful machine. Now that Fusion is superb I can easily switch between OS's for work. I love my Mac!
 
Now it's an Internet music channel, and MacRumors.

Other times it's neoOffice to support the Condo I am president of. Spreadsheets etc are Greek to the rest of the Board members. But that's ok too.

E-mail to support my volunteer "career".

No games. No time. :D
 
My personal computer is the MacBook, I use it for browsing, correspondence, and writing. It's also very important for the keynote presentations I have to do at school. The iMac is my workhorse, it runs Lightroom and Photoshop mostly, and I try my best to learn InDesign and Illustrator. I also do some light gaming on the iMac, and I rip my DVDs on it because it's an absolute screamer with HandBrake.

E-mail, web browsing (Safari/Firefox), YouTubing, messageboarding,

and of course...

Video editing (Final Cut Studio).

I also use my at-work Mac (my trusty iBook G4) for typing up projects/lessons for the students (Word).

Before I cancelled that crappy game, I used to use my Hackintosh to get killer performance out of World of Warcraft (even in Dalaran). Put my Vista setup to shame, even with a better GFX card in it.
