You can get taste of Linux without having to install it
Q: I just tried Windows Vista and was soooo impressed that now I'd like to try out Linux. What is the best way to dip my toes into the Linux pond?
A: Wow. I'm sure that wasn't the effect that Microsoft was going for; however I can't say that I'm surprised.
Though we know your reason for trying out Linux, other readers interested in Linux should ask themselves why? Are you looking to unshackle yourself from Bill? Are you trying to extend the use of your ancient PC? Are you a hobbyist seeking the dark side? If you expect to find a worry-free PC experience out of the box, keep dreaming. Or get a Mac, as Linux does take some effort.
In order to get you into Linux with the least amount of pain and suffering, I'm going to recommend you not install Linux. The first option, and the one I would recommend, is nothing more than a bootable Linux CD; what the penguins call a "Live CD."
