With dual core CPUs coming out in the next few months, we're starting to develop our own real world multitasking tests to see if dual core CPUs will really improve performance in those scenarios. So I'm asking you all, let me know what sort of multitasking you all do and we'll do our best to get some of it included in future articles. Either post in the comments or drop me an email.

My typical usage:SysTray:
CachemanXP (mainly used for free RAM display)
SoundMAX control software
RealVNC server and listening software
BOINC (Seti@home)
Norton Ghost (for auto archiving to my file server)
WeatherBug
MusicMatch Jukebox
WordWeb dictionary
AIM
Norton AntiVirus
AnyDVD
CloneCD systray
Ad-Watch monitoring software
Software running:
A few instances of Calc
FireFox with anywere from 1 to 9 tabs running
Excel
Outlook Express (currently demo-ing IncrediMail)
Internet Explorer (for pages that don't render in FF)
Notepad (I like to write my basic HTML by hand)
Command Prompt
Nero Burning ROM (or cloneCD)
Nero Vision Express (or CloneDVD2)
AIM software
Adobe Acrobat Reader 7 (for viewing program documentations online)
(Sometimes I might be running) Ad-Aware scan
Windows Media Player * or MM Jukebox * or Nero Showtime
(Sometimes I might be running) Norton Anti-Virus scan
A few Windows Explorer windows open for file copying (either over network or to USB pen drive)
WinRAR or XP's ZIPping function

I've run 3dsmax while listening to Winamp and chatting on AIM.Other multitasks include converting 20-30 minute video files from one codec (DivX) to another (usually Cinepak) so it plays nice in some of my DVD editing programs.
I've tried to multitask with Virus Scanning, but it never works. Games run choppy once it starts, it'd be interesting to see if Dual Core can fix that or if HD access time is more of the bottleneck.
My Two cents.

Also, forgot to mention that most of the "multi-tasking" people talk about here aren't really that hard core, since most of those task are running in idle most of the time. In that case if lower latency (quicker response) is required, you can always manually change priority in task manager for the process and reduce the time slice for your OS.PandaBear - Saturday, April 2, 2005 - link
The compiler I use at work is quad threaded, so hyper-thread and dual core definitely help. My experience is that hyper-thread on a 2.8GHz P4 improve speed by about 8%.Other than that I run the debugger and a test tool (both poorly written via infinite loop) and manually set one to lower priority than the other, so my response will not be too slow.
At home I usually burn DVD or defrag in addition to browse web or bit torrent. I think single core is fine for me in this case.

#41 is right on.i'm laughing at most of these comments -
i don't believe anyone who says their typical computing experience involves burning dvd's, encoding divx, compiling code, bt with 4 torrents, photoshop'ing... all at the same time - that's just either retarded or a gross exaggeration.
that being said - i usually have firefox, thunderbird, winamp, mcafee, zonealarm, acrobat, ssh secure shell, vs .net... all open, but the only time i'm truly multitasking is when i might be coding on a project while another project is still churning

I ALWAYS have the following programs open:Outlook express
FireFox (30+ tabs)
Windows Explorer
Winamp
In adition, I usually have at least 2 or 3 of the following open.
Microsoft Visual Studio (C++)
Adobe Acrobat
Word
Excel
Orcad Pspice
LabView
Of course I also run other software. It would not be uncommon for me to have a lot of the above software open and then play a 3D game (HL2, Doom3, UT2004) on top of it.
I generally have 400 to 900MB of memory used at once.

I don't multitask, and neither does >90% of everyone else who uses a computer.I do frequently task-switch, where I'll go from email, to web, to excel, to photoshop, but I'm not doing multiple things *at the same time*. The only time I ever end up really multi-tasking is when I start something that the computer will take a long time to do and (importantly) doesn't require my intervention for the next minute or so. Those cases are pretty damn rare, and are (for me & 90% of others) things which are hard disk, or CD/DVD speed limited. The number of times when I've waited for more than a minute for the *CPU* to do something can be counted on one hand -- one no-fingered fist if you don't include the times when I ran out of RAM and started thrashing the hard drive.
If I was running voice to text transcription software while listening to a lecture and simultaneously recording video and taking notes in Word or Powerpoint -- that'd be a good test. It's the sort of thing I'd really love to do, along with thousands of college students, but I'm doubtful that the software & hardware are quite there yet.
On a mostly unrelated note I think Voice to Text will be 6 different flavors of wonderful if it ever gets reliable. You can Google your text archives, but you can't your audio ones. And you can skim a page way faster than you can listen it.
