Microsoft programmes are fucking overpriced PANTS.

Oops, I forgot I was going to ignore the religious threads from now on. My bad.

So true.

I just use whatever is best for the specific situation/ease of use. Fluidity and willingness to move with trends and advances is my inclination.

Oh well, didn't hurt to try.

Windows 7 mostly, but with odd helping of Linux here and there. I have a minimial install of Debian Stable with openbox and most of the applications compiled from source that I give a whirl every now and then.

At work, I do everything on Red Hat.

Oh wow, didnt even realize i was making a religious thread. im really surprised that this many people voted "not windows". as for previous comments about configuration being required this is not exactly 100% true to the extent most would believe. any fresh system install is gonna either require some configuration or additional software installation (being a notorious distro hopper i would know this). From my point of view (what i use a computer for) many linux distros actually install with "less fucking around required". such as mint, fedora, opensuse, and pc-bsd (not linux, but a preconfigured FreeBSD with almost everything you would need). all these are in the a similar "level of readiness out of box" as Windows or OS X (imo) but this dose not mean it is, just for my style of use. i like to program and do virtualization so most OS's are not ready out of box for this. i feel that all the system's mentioned here would be suitable for a "N00B" to start getting tech savvy. not trying to knock anyone's preference or start a jihad (im the only one who voted BSD so all of you could gang up on me and make me cry). windows 7 actually isnt that bad (compared to previous versions), its just not for me.

Windows Vista.

A lot of people may say it's crap and such, but I don't have much of a problem using it, and see no reason to upgrade to Windows 7 and/or the upcoming Windows 8 for now. And no reason to downgrade to XP either.

All that matters in using an operating system is using whatever works for you. I respect that some may not like X and so upgrade to Y or whatever because it's not as error-prone as X.
