There's plenty of tutorials available on how to dual boot Linux or run it as a Virtual Machine on your current rig. No need to wait and see. Hook yourself up and explore a different world. Ubuntu kicks ass.
Live CD mode kicks ass too
Most or all of the major distributions have a Live CD mode. You can test them without making any changes and then click the install button if you like what you see. Its amazing how you can surf the web while the OS is being installed. M$ will catch up in a few more yrs. Try several different distributions too... don't stick to just Ubuntu or whatever distro your friend uses. I like KDE
so I use a derivative of Ubuntu called Kubuntu 8.04, which has KDE 3!
I will switch to KDE 4 eventually. http://fedoraproject.org/
are very popular and easy to use too! You can find many more on http://distrowatch.com/
the "Page Hit Ranking" allows us to see some of the more popular distros. The easy-to-use PCLinuxOS
(Ranked #6) might be just what you're looking for
Do you like it? I am about to build a new PC system and was wondering if I should install Linux? Never seen it in action and have only used XP. What are the advantages of going to Linux? I am not a comupter enthusiast just a normal user.
Yes I like it. After you find a distro you like using the Live CD mode or a Virtual Machine then install it and dual boot. The OS and software is free, easy to use and easy to maintain. Its nice not have to worry so much about malware and security. They try make things easy for normal users
but if you have trouble chances are your not the first and google your best friend or you can ask on a forum.
Some people are terrified and discouraged by the command prompt/Terminal. Its really not all that bad once you get use to it. I update every piece of software on my PC with two commands "sudo apt-get update" and "sudo apt-get upgrade" Fortunately, they make graphical front-ends
that are more appealing to most people. Either way is easier then updating all the software and patching a M$ OS. Its nice not having to restart my PC every time too. I'm terrified and discouraged by M$ update and the process of updating all the software on a M$ OS.
