You must be my twin. I use Windows for Photoshop and everything else is in my Ubuntu VM.
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 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).
Solaris
Other Unix
iOS
Android
I use the following: Windows 7, iOS 6, Solaris 10, Red Hat Enterprise Linux 5.x, CentOS 6.x, Mac OS X 10.6.8, Android GNU/Linux (other)
BSD/Linux
Android
Linux (other userland)I've considered running Mint or some other popular distro on an old laptop of mine.
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.
Could be someone who is writing their own.
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.
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.
Ubuntu for all servers everywhere.
Server runs OpenSUSE.
On personal server: Ubuntu 12.04
On phone: Android 4.1.2
Anyway, rant aside, I use Fedora Linux on my laptop and a mix of Fedora and CentOS on servers.
Sabayon (surfing\reading\developing)
Fedora (packaging [VM])
Gentoo (server)
...
Plan 9 ([VM] - cpu server; 9pi terminal - developing)
...
Android (tablet)
...
RockBox (Sansa Clip)
Stupid cellular brick (Nokia's s40 Symbian OS I think)
Whatever the Xerox printer is running
Whatever the Panasonic camera is running
Windows (car's IVI)
...
No Mac, Ubuntu or Emacs.
I just can't shake some of the Apple apps (e.g., Aperture, Pages, or Keynote) to be able to switch to Linux full-time.
Windows for gaming
CentOS/RHEL on servers.
so why we still promote windose at work?!
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.
osx, ubuntu, windows, amazon linux, android, ios
