From the sounds of the thread it looks like the OP was just wanting to know of those 3 OS what are people using....I dont think the OP had much interest in who was using Mac, Linux, or some other OS........ Maybe the OP is looking to buy a new system and wants to know which of those 3 most of us are using??

Still with windows xp...Vista gave me too much trouble for gaming so I decided to return to XP and be problem free...well almost anyway :/

Windows is like an MMORPG you need to give it two years before you stop paying to beta test.

I'm glad this thread is just windows, or it might take me a while to post everything I use.  I mainly use Vista at this point.  It's the most solid and stable OS I've ever used.  I use 32bit Vista at home, and 64bit at work.  I've been wanting to go to 64bit at home, but I have so much stuff on my computer (approximately 700-800 gig) so I've been lazy about getting around to it.

I still have a partition of XP on my home computer, and I think I've booted into it about 3 times over the past 2-3 years.

When I had to replace my laptop I decided to put 7 on it, and if I had more time I'd put Vista back on it.  It's got the stability of Vista, but needs another beta or two as it's just not ready for the big show.  For every step it takes forward it takes at least one back.

I laugh at all the people that whine about performance in Vista.  Vista & XP gaming in DX9 have been even for some time now.  Usually if someone says that it's slower I take a look at their computer and they have so much extra garbage running because they won't turn off a single thing their application shoves in.

Linux is fun and I love to dabble with it, but the only way I would use it full time is if the only other choice is a Mac.  When they are working they are great.  The first time you run into a problem and you realise you need a good knowledge of text commands is when you realize it's not the 80's anymore and you move on to something else.

I've got nothing against Macs, I fool around with mine from time to time, there is just something about the incredibly poor layout of OSX that makes me want to schoot someone if I use it for more than an hour.

 I'm using all three. But I primarly use Vista 64bit. It's a solid as a rock.

I use ubuntu and xp.

I tried vista but went back to xp.  I will try windows 7 at some point.

Primarily I use Windows 7. Its stable, easily compatible with my games and apps, and is able to use my hardware and make it work very nicely.

I did have XP 32bit, but... I needed 64 bit for my upgrade, so I just got W7.

Vista 64 on all computers i have.

I testes W7 is beautiful, i cant wait for release.

Linux is not an option for me.

Currently between my two desktops and net book, I have 3 XP installs, 2 Ubuntu installs, and Windows 7. I mostly use XP at the moment.

But to be honest, if Windows 7 wasn't going to be unavailable in the future before it's officially released, I would uninstall all of my XP partitions and install Windows 7 as my Primary OS right away! The thing is beautiful. I have it on my old Pentium 4 machine and it runs just as good as XP on my quad core. I love it, I can't wait for it to be officially released.

BTW, I love seeing all the people claiming that Vista sucks because 3rd parties have crappy drivers for it.

Windows Vista x64 here.  My wife has Vista x86 and my daughter has XP Pro x86.  The only game problem any of us have is trying to play Spore on my X64.  It just doesn't work.  I think it's ATI's drivers though.

IronZ

I'm going to echo I'm now using Vista 64-bit Home Premium here.

(Was using 32-bit Home Premium but the 3.2 Gig limitation was annoying)

Besides a blue screen with a reinstallation of a standard PCI bridge to standard PCI bridge driver on reboot, when first waking my PC from sleep, it has been doing fine. It is other wise solid.

(Listing these low specs below in case it's a combination of hardware that did it)

Motherboard: MSI K9A2 Platinum

CPU: AMD Athlon X2 5000+

RAM: Corsair Dominator DDR2 800/1066 4 GB

Hardrive: Western Digital SATA 320 GB 7200 rpm

Video Card: VisionTek Radeon 3870 Overclocked Edition 512 MB

Sound Card: Creative X-Fi XtremeGamer

Edit: Added Memory amount for Video & RAM

Well, that was the reason *initially*. But it's been mostly solved, save for the odd Nvidia driver fault. The Windows Display Driver Model which carries on in Windows 7 is the future, and Vista took the brunt of the blow because it was the first OS to require it. 3rd party developers had to adapt, and Windows 7 will profit because of it.
