All hands down... Linux / Unix is the way to go!!! Even Mac OS has started using BSD since their OSX... Its not too long that Windows will be just a thing of 90's... Most the the devices are already compatible with Linux/Unix because of this stability and security compared to WIN... I do use win coz i have been using it since win 3.1 (wasnt OS then) but i also have Linux box that i use for various test purpose.. Any of you guys wanna try linux without even installing it.. try "Knopix" you just boot ur pc from CD ROM and LINUX is in... reboot without the CD.. u r back to your Windows.. no installation required.. but very good tool! ENJOYEEEE!!!
