I was, until I got a laptop for christmas with windows on it.

Servers - all Linux (starting around 2001).
Desktops - all WinXP (although most of them run Linux as a Guest OS under VM - plus a handful of laptops that either run Linux only or dual boot).

Not sure what we'll do in 2008 when Microsoft forces the move to Vista by not selling WinXP OEM anymore. Hopefully by then, Vista won't suck.

My primary desktop computer and laptop both run Linux, but all my other PCs run Windows XP/Vista.

At home, yes--I'm 100% Windows Free. Four computers, all Linux, all the time.

I have an unopened box of windows XP Pro sitting on a bookshelf--it was given to me last summer at a teacher computer science training workshop by a Microsoft Rep. I have not been visited by any temptation to install it.

None of my computer peripherals are MS products either.

In this particular historical moment, I ban Microsoft on my PC and I install only free/open software if I can.
When the free/open software will be established I'll install Microsoft packages on my linux/BSD system.

I own a XBox, a Sidewinder game pad, and a wireless keyboard and mouse set. Plus there are some M$ programs on my Macs.

Spent AUD$47 last year (for MS MCE USB remote). This is my only contribution to Microsoft since Win2k and MS Office 97.

Everything else has been MS free.
(No Xbox, Zune, Joysticks, mice, keyboards, etc).

ALL my boxes use either Linux or BSD.
(Arch Linux, Debian, FreeBSD and OpenBSD).

NO Windows, MS Office, Visual C++/C#, etc.

I've even removed Windows off my ThinkPad...Even the "Designed for Windows" sticker! (Looks so much better when you remove ALL those damn stickers!)...And yes, I got powersaving features and ThinkPad buttons working fully.

Only Linux here. And I don't use any w32codecs or MS ttf fonts on Linux like some other folks.
