(Based on this Windows Taskbar thread.)
Mac OS X users, what’s in your dock? I have, from left to right:
Finder (duh)
Simcity 4
Tranquility
InDesign CS
Illustrator CS
Photoshop CS
Appleworks
Word 2004
Powerpoint 2004
Excel 2004
Safari
Mail
iChat
iTunes
Adobe Reader 6.0

Folding@home
MPlayer
From top to bottom: (left side of the screen) from memory as I’m at work:
Finder
Safari
Ichat
GarageBand
TextEdit
Sherlock (or whatever it’s called now)
Oh, there’s more. I’ll update when I get home.
I’m one of the Dockless ones. I suppose something’s in it (the Trash can if nothing else) but I wouldn’t know, it’s never running long enough for me to notice.
Hmm… from memory:
Finder
Mail
Firefox
Safari
iChat
Address Book
iPhoto
iTunes
SubEthaEdit
MS Word
Transmit (best FTP client)
GarageBand
XCode
finder
AOL Communicator
iChat
AOL

Address Book (unused, but I’ve not removed it for some reason)
Calendar (ditto)
iPhoto
Finding Nemo
iTunes
Word
Excel
System Prefs
Quicken
Calculator
iMovie
I keep the dock on the left side of the screen. With a wide screen iMac, that just seems the best place for it.
Mine’s left to right. My screen’s only 1024x768, else it’d be on the left.
Finder, iTunes, Quicktime Player, VLC, System Preferences, HP Scanner, Image Capture (for the digicam), TextEdit (my HTML editor), AppleWorks, GraphicConverter, Preview (bye bye Acrobat Reader!), JediKnight2 (IRC, though I never use it), Poisoned, Safari, iChat.
I’ll let you know on Thursday…my iBook left Sacramento this morning.
it’s like christmas, I tell ya! Christmas!
Mine’s on the right side of the screen; there isn’t much room at the bottom, and somehow the right feels more natural; maybe it’s because the mouse is on the right.
Finder

Mine used to be on the right, but since I got a second monitor (flat panel Apple Cinema Display! Woo hoo!), I moved it to the bottom. Too long to move the mouse all the way to the right of the second monitor to reach the dock…
Finder
MacReporter
Final Cut Pro
Photoshop CS
iChat (don’t know why; never use it)
Address Book (ditto)

Trash
I use DragThing so pretty much ALL of my apps are in play. I divide them by use (all of my video editing apps on one tab, my internet related apps on another etc…).
I love DragThing…been a user for a long time.
My Mac is my work computer, so it’s kinda dull.
Bottom, from left: Finder, Outlook Express, Word, Internet Explorer, Adobe Photoshop, Quark Xpress, Olympus Utility, AppleWorks, Acrobat Reader, iTunes, Sherlock, Trash.
I am a left side of the screen dock guy myself.
My dock just has the standard apps that come with OS X…since I just got my iMac a couple weeks ago and am still working on customizing it, getting software, etc. My first Mac!!!
And to be honest, I know how to add stuff to the Dock, but not how to remove stuff! Looks like I’ll be playing with the Dock when I get home.
I am surprised by the number of people that don’t have GarageBand in their Dock. Outside of setting up my mail and iTunes Library, GarageBand is the only thing I used so far and I love it. Incredibly easy and fun!
Drag an icon from the dock to the trash can to remove it from the dock.
I have mine arranged so that each icon is visually distinct from the ones on either side of it, to decrease the chance of mis-clicking.
Finder (blue square)
System Preferences (white square–here the system broke down a bit)

X Windows (White square)
Powerpoint (orange P)
iTunes (Gray circle)
Skychart (Black square)
Interwrite PRS (purple circle)
Preview(blue square)
TeaTimer (White, uh . . . teacup-shaped)
I swap stuff in and out of my dock constantly, according to what my current project/obsessions are.
God, I don’t know if I want to type this all out or not, but what the hell…

Phew…after typing that I think I need to clean it up a bit.
Actually you don’t have to drag it to the trash. Simply drag it off the dock and it poofs into a cloud of dust and goes away.
IIRC, mine has:
Finder
Mail
InDesign CS

Alias to the Applications Folder.
