for me virtualization is everything - I hate if I have to shut down my laptop.
btw, intel's new processors support virtualization - and on dell machines, by default virtualization support is off. have to turn it on from bios setup

These days i tend to use Kubuntu as my primary OS and I have a VM that runs XP perfectly well inside it. Unfortunately some GFX card features that are used by the latest game engines haven't been ported to Cedega yet so if I want to play DirectX games with all the features working I have to reboot in an XP partition, I guess i should be glad that none of the games I play requires directx10 yet. This setup does have a great advantage that while I'm working at home I don't skive off for 10 mins playing computer games.

1 Debian 4 (The best choice so far)
1 win xp (for my vb.net appz)
1 win 2003 server (for asp.net development)
1 ubuntu (to run them all in a vm 
If i could run asp.net and win apps in debian out of the box , i would be the happiest man in the world!

I still find that having separate boxes with different OS's is the best option. Currently 3-Vista, XP, and some web server flavor.

But that would be rather costly investment of real estate, time, effort of management, energy to run around to over see the systems and cost of software right?

Client provides most of the machines, one's a laptop, I typically only use one at a time anyways so the others are off, the 3 LCD monitors run off solar, I have a large desk, and the cost of software is nil because of my MSDN subscription.
Contrast that with the cost, in time, of setting up a VM and the time consumed because of lower performance. The benefit of a VM is that it can be restored to a known state, which is good for testing, not, as I interpreted the question to imply, for development.

I'm like that, only I do keep a library of ready installed VMs. They make EXCELLENT demo utilities. You have something pre-recorded, install what you need and ship to the client. But I agree, nothing beats having a dedicated box.

One for Windows XP, one for OpenVMS.
But if my employer wanted to get me an Itanium system I might be able to run both on it. (Nah, I prefer the Alpha.)

I half disagree on the Vista thing.
It is a system. A huge bloaty system.
However, I do agree that it's not operating.

Look. The half-assed one voting creatures are out. You can't say your opinion loudly. If you do, they'll vote you 1. However, there are only 2 or 3 of them.

Why do you care what people will vote?
Are you giving your opinion . . . or theirs?

I guess I am the only one here who likes Vista Just love this "Start Search" box.

Yes, Vista is worth buying for its "Start Search" box. This wonderful little search option outweighs all the other nuisances of this shiny unfinished bloatware operating system. It boots fast on my dual core machine with 4gb of physical memory. Amazing, isn't it? 
And finally, does it really matter if I like Vista or not? I am asked at gun-point to build software that would run on Vista. Because I am a developer, and I need to secure my job.

Come on, with the price of hard drives now-adays does it really matter, I mean even here in the UK you can pick up 500GB sub £40. Plus the added bloat is for me worth the price for the speed with which Vista installs.

Right, Windows is just a GUI on top of DOS... but why can't I get it to boot to the command line like it used to do...? I really dislike waiting for it to get all the way up just so I can open a DOS box to get some work done.

|

Not anymore!
Although versions 1-4 actually ran on top of DOS, as of version 5.0 (Windows ME and 2000) the DOS core was completely removed from Windows.

My main development PC is Windows XP, but I also use virtualization for Multi-OS support. Also, Microsoft has started releasing VPC images for major beta releases of tools and servers.
It is a lot nicer to delete a VPC image than uninstall something that doesn't uninstall well!

Seriously, kinda a poorly worded question. But I guess it does allow to see how many different OS'es people use.

Have Win Vista Home Premium (soon to be WinXP Pro SP2) on bare metal. Everything else in virtual machines, using my favorite: VMWare Workstation.
Windows XP (use it a lot for testing potentially-malicious software: Snapshot undoes damage in one step; also development machine, as my old apps tend to work without tweaking. i also have to run office 2003 in this, since won't install on vista)
Fedora 8 & OpenSUSE 10 (for Unix/Linux development and testing)
Potentially Coming Soon, after current project, for testing and probably temporary:
EnGard Enterprise Linux (the supposedly super-secure one)
CentOS (heard a lot, but it's web site isn't informative)
OpenBSD (still one of most secure)
FreeBSD (for testing)
QNX - best real-time OS out there
MontaVista Linux - second best? we'll see
SkyOS or MorphOS - saw video of 15s load time. amazing for quick chores. must try it.
Yellow Dog Linux - it is the one on PS3's. will need to be familiar with it.
NetWare - ok, just kidding... (I would just be asking to be hacked )
Later. Hope someone saw something they may like to try in the list. It won't be a silver bullet though: like werewolves, they don't exist. (skin conditions dont count...)

At last count, Xena (otherwise known as "The Big Black Box Full of Vogons", due to the size and stying of the case) had:
- Vista x86 (primary boot)
- Vista x64 (are you feeling lucky?)
- Windows XP (drab but fast. Unless you are using Explorer)
- Windows XP64 (are you feeling really lucky?)
- Windows Server 2003 R2 (for those "I want to play with domains" moments).
The system drive on this machine lives in a lockable caddy, so multi-booting is tivial. Far simpler than mucking about with boot managers.
Then of course there are around 20 VMs of various shapes and sizes on their own 500GB drive. It's a fun system to use, especially when running through a 24" widescreen TFT.

To sum it up: You have a pure Windows machine.
That's not what I thought about when I read "how many operation systems"... 
My notebook runs SUSE 10.2 and Windows XP Home. That's what I call dual boot ... ah, wait, sometimes it's triple boot! Linux reliable kernel, Linux self-compiled kernel and good old Windows.
