Windows 8 with Virtual Box running Ubuntu. I do all my dev work in the VM, and everything else in Windows. I used to be a die-hard OS X user, but then I realized I could build a beast of a desktop for less than half the price of a Pro.
I use different OSes for different purposes. I use Windows in Parallels on a Mac, alongside several other Macs running various versions of OSX. I have a FreeBSD 9.1 server and an Arch Linux server, as well as a bunch of VPSes I use in my cluster.
I also have a laptop I use to run AROS and an older laptop and a couple of PCs that run Plan9. To be fair the PCs and laptop are mostly switched off, I mainly used them for distributed processing.
I desperately want to run AROS as a main OS but it's just not there yet for me. I've got haiku on my list of things to try as a personal desktop OS.
I use a mixture of iOS, stock Android and custom-built cyanogenmod firmwares on mobile devices. Granted, Android is technically Linux but I'm surprised neither that nor iOS were down as options.
I reluctantly started to move away from the Amiga as a primary OS in the late 90s and finished some time in the mid noughties. I've kept going back to AROS in the hope that I can get something Amiga-like going, but there's so much more that needs to be done to make it usable on a modern laptop.
I loved Amiga as much as the next guy… I remember installing a Kickstart ROM as a fourteen year old. But what desktop paradigms does Amiga offer now that aren’t present in other OS’s?
When creating a poll like this, it would be useful to specify the question in a bit more detail. Do you mean what is your primary OS or do you mean responders to upvote every OS that they use even only rarely?
I use OS X and Fedora at home and Ubuntu, RedHat, AIX, Solaris and Windows at work, so I upvoted every option except for BSD (and, strictly speaking, OS X falls under BSD too).
Android ought to fall under Linux (Other), but he should still add it. He should also separate GNU/Linux (other) and BSD/Linux categories; see how many people are using BSD userlands like obase and magenta. So,
GNU/Linux (other)
BSD/Linux
Android
Linux (other userland)
What do you like about 13.04? I have it on a machine here but I mostly do 3D animation work on it, and don't really interact much with the Ubuntu-ness.
I don't mean 13.04 in particular, I mean Ubuntu in general (though 13.04 does come with some nice UI updates). Before I became a developer, I used Windows. When I started trying to get into more serious development, trying to do it in Windows was just awful. Ubuntu was a breath of fresh air. From an interaction standpoint, minor things like workspaces, always-on-top, etc are great for my workflow. Things often take more work to get up and running due to various issues like hardware incompatibility or lack of software support, but once you do get it running I feel like it's smoother and more stable than Windows. Software management (e.g. installing and removing packages, adding and installing from various sources, updating) is more logical and consistent than for Windows (e.g. downloading and installing executable, managing updates individually).
This is all subjective and I wouldn't consider myself an expert on either OS so I could be wrong on some accounts, but that has been my experience.
I see one vote for Other without any comment explaining which other OS it is. I'd be interested to see what pops up: Android, ChromeOS and FirefoxOS are really Linux variants; I suppose iOS stands on its own. VMS is certainly in use but probably not on the desktop. I suppose there are some Solaris folks...what else?
iOS is OS X. I'd bet it's someone who either didn't realize that the two popular mobile OS's are variants of common desktops, or someone who is playing with something like BeOS or Plan 9 or some other more obscure OS.
Android is not really a variant of a desktop, it just uses the kernel, which is not desktop specific in any way, and everything above (from the libc up) is either custom or non-desktop specific.
At home I use a Windows machine, two Arch Linux boxes, and an ARM Arch distro. I have a VPS with Ubuntu on it. At work I mostly use FreeBSD as my workstation and the production server cluster uses it. We have an ubuntu box in there somewhere too. Most of the office is using mac, so if the mood strikes me to go mobile with a laptop I pick one up from a stack of the things and wonder around with a mac. My hacker space has some old sparc machines I was thinking of grabbing... but I don't need another nightstand.
If you asked me this a few years ago, I'd say I used z/OS quite a bit too.
I use a Macbook Air, but spend most of my time in Ubuntu. I've just come to like doing all my development work in it. I use OS X in places where I run into services that don't support Ubuntu.
OS X for the main development, on a relatively venerable 17" 2009 MBP, so that's the single upvote I offered.
But, the code's deliberately platform agnostic, and I do secondarily maintain a Windows version, under Parallels, for the DirectShow filter build. I'll likely bring it to Ubuntu later as well, for render farm deployment.
Windows at work because I have to, and Arch Linux on everything else with a Windows partition on my main desktop's home drive to play games on and any other miscellaneous things I needs Windows for (not much at all these days).
A bit picky about my Linux desktop experience. I check in with Ubuntu at every .10 release to see if it yet passes my picky standards. It was getting much, much closer in 2012. I'm actually looking forward to this year's.
Upvoted Mac OS X but really there should be iOS on there too (and Android for good measure) since I'm on there doing stuff (and sometimes it's real work!) almost as much as I am OS X!
Windows 7 Ultimate 64-bit, with an Ubuntu 12.04 64-bit guest running inside VMWare Workstation. It's usually always on, and I use the VM heavily for dev.
I use exactly that setup too. I'd spend most of my day in the Ubuntu machine and the rest in a web browser on osx. The only reason I have both is that I used to need photoshop.
