If you will browse to
you can download an image and then burn a KNOPPIX Linux Live CD, which is based on the Debian GNU/Linux distro. This runs from the CD using a ramdisk on your computer, and will not alter your hard drive or add a single file to your computer. (NB: I would suggest that you download it to your existing Linux distro, if you get version 3.3, as many people reported problems trying to burn a CD of v3.3 under Windoze.)
KNOPPIX has all the software, and the "cool stuff" you are looking for, right on one CD. And if you decide you like it, you may then install it on your hard drive. I've run KNOPPIX on both my workstation and my laptop. It detected all my hardware on both computers. Configuring my nics was very easy. After a short investigation, I installed it on the notebook. I've got Debian on the workstation, and a LQ guru is helping me to do a lot of custom configuration with that system, so I didn't install KNOPPIX there.
KNOPPIX was a quick and easy way to migrate from Mirco$loth to a Linux distribution. I think you'll be pleasantly surprised!
Of course, one could ask you some questions, such as:
1) what distro are you using?
2) what software do you believe you "can't live without"?
3) What are the apps, cool desktop environments, monitoring utilities that you use on daily basis and absolutely have to have?
If you are referring to the thread MasterC started about posting a screen shot of your desktop, I believe most of them describe what they are using. However, I abandonded the thread, because most of the screenshot links seemed to be broken.
