So what is your other OS?

Ubuntu 9.04 as my development computer
BeOS 5 for web browsing and general purpose stuffs
Windows Vista for warcraft 3

I seem to be the only one here who has never used Windows! At work, I went straight from MSDOS to Linux; at home I went from QDOS (Sinclair QL) to Linux, via a Q60 computer that had them both.

I'd like to say I have Linux, Syllable, and Haiku, but I haven't persuaded Haiku to install yet.

Desktop:

Haiku r1a1, Haiku nightly, BeOS r5 pro Ubuntu.

I have not booted into Ubuntu in about three months. There is no Windows on the Desktop.

eeepc

Windows xp, haiku r1a1

I boot Windows when I need to connect to a wireless network that is encrypted.

Ubuntu with gnome-core as primary and Xp for printing, (I have a Lexmark printer, abysmal support in linux). Looking forward to Haiku as primary.

Might as well.

- Solaris for home and programming.

- Spurenelementemangel for work.

I usually use Mac OS X as my day to day for my main machine. Web pages, videos, graphic work, web & e-mail.

Just built a Hackintosh to replace a PPC G5. Since OS X is not working yet, I am running Ubuntu Studio 9.04 on it for day to day. Will keep it as dual boot, as I really like Ubuntu. This machine also has Windows XP & Haiku on VirtualBox. I have 3 HDs, so I will try to see if Haiku will work on the hardware.

My work computer is an G4 Power Mac w/ OS X. Just e-mail, web, MS office.

My laptop is a Powerbook w/ OS X. Just for web, email on the go.

My extra is a G3 iMac currently Xubuntu 6.06, just because it works without messing with it.

Great new year all togehter,

my main os is ArchLinux since 3 years now. Xfce is the desktop I belive it's the best.
ArchLinux is the best Linux distribuition I found on the web. But in my opinion Linux has some stranges. You can have a great system, but you have to do it by yourself. There is no "perfect" distribution. Linux is not Linux.
For PCs these days, there are better solutions as showing a TEXT-console on the screen to edit the system.

your Finest Bug

Desktop dual boot: Linux Ubuntu (now 9.10)and WXP for some hardware / software incompatibilities (e.g. dell/lexmark printer, MSN and ITunes).
Netbook dual boot: Linux Fedora (now 12) and WXP for hardware driver incompatibility UMTS/HSDPA modem
Laptop: PC-BSD 7.1.1. (Free BSD 7.2 stable)

On desktop in VirtualBox on Ubuntu lots of try-outs, Haiku is the one I keep (trying out) :-)

Winxp pretty much everywhere. I do have 3 dedicated haiku machines

What a shame I couldn't keep all my old machines and O.S.'s.
Everything from an IBM-PC @ 4.77 Mhz up to my currently ageing Athlon 2.7Ghz.
Wow. That's 8088, x286, x386, x486, x586, x686!
Everything from DOS 3.1 up to WinXP, SuSE 11.3. PCLinux and Haiku.
I even used OS/2 Warp and NT Server 4 :)
Somewhere there are people who have kept all that stuff, and one day, if the world doesn't end in 2012, they will be millionaires.

I use XP every day, and:
BeOS, Haiku, SuSE Linux, for fun.
Dolt that I am :)
And I still have time left over to cut firewood by hand, build house additions and outbuildings, and feed every bird and raccoon for miles.
Hehe life is fun :)

The desktop gave up the ghost ... using the same hard disks. Ubuntu still boots as well as Haiku. I am using recent builds only. I boot Linux once in a while to remind me why I use Haiku. Beos does not boot, but I keep the partition for the software and if I ever change to a mobo that it will boot on.

The eeepc laptop still has Windows xp for encrypted networks, but I use recent builds of Haiku now.

I used to be Amiga user, and after conquest the paradise I run to the Duron 650 diaspore, where only BeOS R5 was reasonably usable. In These days, I hate my work comp, MAC Quadra&system7 - no multitasking, bad stability... After my Duro's died, I cried upon XP for few dark ages on next Athlon, but freedom of the Bee was only myst of the myth. I tried averything I found, AtheOS, QNX Neutrino, Syllable, AROS, Linux... and in the end, now I'm using MAC MINI, and AthX2+W7. But I never maked piece with it. Well, Mac is cool, but the Mach kernell is really slow, isn't it. And W7, yea, maybe they are really best Win ever seen, but, You know, It's still only Windows... And this new era of multi core procs, It's scream for... for... where I saw OS with natural ability we need...

OSeX Panther :D

Desktop: Mac OSX 10.7
Laptop: Windows7 and 3 Haiku Partitions (Main, Dev and a pristine A3 installation for testing and emergency reinstalls)
Netbook: PCLinuxOS

I have started working on Haiku. I used to be application programmer turned HTML5 game developer. I am trying to port OpenJDK and writing Haiku API wrapper for GTK, wxWidgets, etc. to port as many applications as possible. But mainly concentrating at porting Virtualbox OSE, Inkscape, Gimp, geany and latest firefox first. Also interested in working at x86_64 port and in future probably starting a production deravitive of Haiku with UI inspired from haiku and applying it to Adwaita theme. Like replacing white with yellowish color at places lol. But yeah, lot of work to do. Haiku is really my fav OS. Also, implementing user system and making it a secure platform would be a wonderful work to do. Currently I am at my one of key projects, after completing it I would get 3+ hours a day to work on Haiku for free :)

On main question lol. I deletd crap windows partition. I have Haiku R1 Alpha 4.1 x86 and Ubuntu 13.04 x86_64 as my main OS. In virutalbox I have windows XP as an emmergency system to use when I need to run a software which isn't available for ubuntu and wine can't emulate it. But I didn't need it to boot ever as of writing this.

Dragonfly BSD for everything from coding to gaming.

I have a dual boot Windows 8.1 / Haiku OS computer for gaming / working
I also have a Macbook Air (2011) for emailing and downloading.

I've used Linux since last using W98 in 1999. Various distros to start with, but standardised on Debian & Debian based. Spent several years with pure Debian, transferred to Crunchbang, now using AntiX (also MX-14).

Another distro I use is SliTaz, it is so small, 40mb, it uses Busybox instead of the usual GNU utilities.

I have used FreeBSD in the past, but it wasn't so good as Linux for me.

But.... I still like to try other OS's, & so here I am now re trying Haiku. :)
