Off Topic and apologies if you already know all this.
Just a note for any Windows users who might be thinking of trying out linux.
Best way is to try out some of the Linux Distributions (distros) before going flat out and installing one. This is important because not every distro might support your particular mix of computer hardware or you might just hate the 'look-&-feel'.
Most distros have a 'live' version, although that is not always the case. This comes in the form of an 'iso' file, ie a disk image. Modern computers generally will boot from a usb drive so there is no need to burn the iso to a CD/DVD. Quicker boot time and saves wear and tear on your DVD drive. No usb booting? There is even a way around this for older computers, the 'plop' boot disk.
http://www.plop.at/en/bootmanagers.htmlInstalling a distro iso to a usb drive is no longer difficult, there are utilities for this. One of the originals is 'unetbootin', there are versions for Windows, Linux and Mac. see:
http://unetbootin.sourceforge.net/Another resource for this is
http://www.pendrivelinux.com There are alternatives there, mainly for windows. One of them YUMI I found to work quite well.
So if you have a spare hour, fire up a linux and see how it performs.
