I haven't tried the Trisquel GNU/Linux 6.0 OS but I have used Ubuntu, Fedora, and SLAX which are all Unix/Linux based operating systems. What I can say is that they are different. You will have to learn the new interface, new keyboard shortcuts, etc. And also know that all your existing softwares won't work on this (Trisquel GNU/Linux 6.0) operating system because they are made for Microsoft Windows operating system. To use your existing windows softwares you have to use special software like 'Wine' to make your windows softwares work on Unix but don't expect it to work 100% because they just try to create the windows environment to operate the software. Unix operating systems does not recognize the .exe extension files, what they understand is .deb .dmg etc for software installation.
Because these operating systems are not as popular as Windows, there is relatively limited help and support available when you encounter problems using the operating system.
Also in my opinion their interfaces (Ubuntu, Fedora, and SLAX) are not as beautiful as windows interface maybe because I used to windows.

You can install the Trisquel GNU/Linux 6.0 operating system in a virtual environment to try it out before actually installing it on your laptop as main operating system

chuks315, thanks for your reply. I doubt if I'll be using Trisquel for a while yet. I've used Ubuntu for a few years until recently when it accidentally failed. I have Ubuntu 12- and Suse 12- but I'm waiting for a more favorable environment before re-installation of either OS. I didn't have much success with 'Wine' but dual booted with Win XP instead.

I appreciate all of the information that you have passed along to me, as it will come in handy in the near future. Thanks, again.
