Vista 64 Home Premium. Have had no problems with it whatsoever since Sp1. I'm looking forward to Windows 7.

" I'm running Windows 7 on a tower I built from scratch. So when this thing expires on me I'm screwed, cause I dunno what to install. "

It expires the summer of 2010. You have some time. Just buy Windows 7 when it comes out. "

Oh Windows 7 is gonna release at the same time the beta closes? "

OSX 10.5 but i'm not sure if that's Leopard or what.

My desktop dual boots Vista and Win 7 both 64 bit, my laptop duals 32-bit XP and Ubuntu. I dabble with the Win7 and Ubuntu, neither of them get used much. I don't mind Ubuntu, but I don't see why I should use it when I've got the XP license. Haven't spent enough time with Win7 to have all of my programs installed to it, otherwise I'd probably use it more.

Ubuntu 9.04

Ubuntu 9.04

i'm running windows XP 32bit. vista still has some problems that i have seen from my friend's computer. i don't enjoy buying a new operating system like that.

I run Vista Ultimate.

Vista on my main PC, and XP on my netbook. Probably will upgrade to Win 7 once it comes out though.

Windows 7 RC

So far a much more positive experience than Vista. The biggest complaint I have is that after closing a resource intensive program (game, photoshop, whatever) W7 tends to hang for a bit, which XP and Vista never did.

Leopard

Windows XP! and wtf?! Vista is winning this poll??! Who knew.

my computer is a beast and thus runs vista fine ;)

Google Chrome: Hype Edition

I'm using Windows XP Professional SP3. I might upgrade to Windows 7 once it comes out.

Ahh ME, how horrible you were... anyway I'm currently running OSX Leopard

Windows 7 RC. Maybe the best Windows OS I've ever used.

I do most of my stuff under Mac OS X Leopard on my Mac, when I'm going for some gaming I use BootCamp for Windows 7 RC. Love them both.

Im using the Windows 7 64 Bit RC

Got me Mac OS X Leopard, but will upgrade to Snow Leopard since I have been reading that in terms of speed it is the shit.  But I also have WIndows 7 RC on bootcamp on my Macbook Pro so I can play any PC games that I want, also there in case Star Wars the Old Republic doesnt come out on Mac OS.

vista at the moment, but eagerly looking forward to windows 7 upon retail release!

Snow leopard isn't out yet BTW. Unless you're a developer and Apple is seeding it to you.

Vista and Kubuntu mostly.

I can't believe people still hate on Vista, since SP1 I haven't had any problems with it what so ever. I'll admit that pre-SP1 it was pretty glitchy(damn thing would blue screen every time it went to sleep and sleep wouldn't turn off) but since SP1(it's onto SP2 now) I haven't had any problems.

Windows Vista 64-bit.

Linux. Thinking about getting a copy of Windows 7 to dual boot and satisfy some cravings.

I run Windows XP on my desktop and my laptop. I wouldn't mind Vista but XP gets the job done fine for me.

Shocked that Vista is #1. 

Win7 RC

I dual boot Ubuntu and a stripped down version of Vista.

I tried Windows 7, and I am definitely going to be replacing my current Vista setup with that, but I'm going to wait until it launches proper.

Vista currently but when my Windows 7 comes in its going straight to that!

custom XP until windows 7 is for real.

I run Ubuntu 9.04 (not dual boot) its awesome but some games just wont run through wine which sucks

right now i'm running Vista Ultimate 64-bit. 
 
however, I get Windows 7 Ultimate 64-bit for free 3 weeks before it is released....so that will be awesome. 

" @lilburtonboy7489: I am jealous of you.  How are you able to get it early?  I wish I could get Windows 7 this year, but I won't have to money to get it and all the games I want.  Also, I am fine with Vista right now. "

Damn you Best Buy employees!

Mac OSX 10.5.8 
 
Soon to be Snow Leopard.

Windows Vista 64-bit.

Ubuntu.

leopard FTW

Windows XP SP3. Gonna stay with this until I upgrade to Windows 7/Windows XP's long term whatever support is over. I think that'll be around 2011. By then hopefully SP1 of Windows 7 will be out. Then I'll just buy that.

My Main unit is Windows XP(Plus Win for Work 3.11 under DosBox) Both Mom and Sister have Laptops Running Vista.

I use XP for that only computer that I have. I'll probably get a new laptop when Windows 7 comes out... 

Vista.

PPL stop complaining about vista, if you have a notification problem....TURN IT OFF.....ive tried going back to xp, i cant, vista is a step up deal with it

Dual booting Windows 7 RC and Vista. I like 7 and going to get it when it comes out.

linux mint

hmmm.... how are people running Snow Leopard right now?? I wonder, I don't think I want to know, I rather wait till its ready.
