So, I am rather interested to see the ratio of OS X/Ubtunu/Windows 7/Windows 8/etc. users among TPT players.

So which operating system(s) do you guys use?

I personally use Gentoo and Windows XP.

Current stats:
Number of users with each os, multiples for the same user not counted twice:
Windows XP: 7 (MiningMarsh, Fakenublet, fireball5000, greymatter, whizkid22298, Kikinicij, Dingolo)
Windows 2008: 1 (bigpig)
Windows Vista: 3 (hittox, whizkid22298, billion57)
Windows 7: 19 (soccermitchy, nucular, therocketeer, nmd, GOKOP, jacob1, boxmein, mniip, GreenFireDragon, ristovski, cyberdragon, wolfy1339, whizkid22298, firefreak11, Kikinicij, hamada, plead-for-destruction, Poorsoft, RAYZR, cinapowder24)
Windows 8: 8 (hittox, jenn4, GreenFireDragon, greymatter, wolfy1339, whizkid22298, Kikinicij, hamada)

Debian: 4 (soccermitchy, jacob1, mniip, ristovski)
Kubuntu: 1 (nucular)
Ubuntu: 3 (nmd, boxmein, firefreak11)
Pinguy: 1 (firefreak11)
Gentoo: 1 (MiningMarsh)
Arch: 1 (ristovski)

Mac: 2 (fireball5000, firefreak11)

People who primary / secondary different OSs
Primary Windows: 17 (nucular, nmd, Fakenublet, jacob1, boxmein, hittox, jenn4, GreenFireDragon, fireball5000, greymatter, cyberdragon, wolfy1339, whizkid22298, billion57, firefreak11, Kikinicij, hamada, plead-for-destruction, Poorsoft)
Secondary Windows: 4 (soccermitchy, MiningMarsh, mniip, ristovski)
Primary Linux: 4 (soccermitchy, MiningMarsh, mniip, ristovski)
Secondary Linux: 5 (nucular, nmd, jacob1, boxmein, firefreak11)

Those who use mutliple OSs versus just one:
Two or more: 10 (soccermitchy, nucular, nmd, MiningMarsh, jacob1, boxmein, mniip, GreenFireDragon, ristovski, firefreak11, hamada)
One: 19 (therockeeter, GOKOP, FakeNublet, hittox, jenn4, fireball5000, greymatter, cyberdragon, wolfy1339, whizkid22298, billion57, Kikinicij, plead-for-destruction, Poorsoft, BigPig, Dingolo, RAYZR, chinapowder24)
