Hey, wait a minute. Why are you getting Linux? Some of the reasons why people get it is because it has:
1) Variety of customization
2) Open source code(most)
3) Continual updates
4) Security(not vulerability-wise, but .exe wise)
5) Does not get 'fat' because it does not have a registry(arguable)
I forgot the rest, but you must be at least an adept computer user. There are so many Linux advocates that say that it is much easier and intuitive than other operating systems, but that, in most cases, isn't true. Why would that be? Well, first of all, there are several desktops you can choose from, which could confuse the average user. Also, since there are so many distros(aka. distributions/variations) of Linux, it could also be daunting to one that is attempting to download software packages for their own distro.
Now, that brings me to the next point. There are many people using a distro that really might not suit them, since some advocate for their own favorite distro without regarding the needs of the person(s) asking for suggestions on what to pick.
Some suggest that Ubuntu would be a good first choice for beginners. Others suggest that Gentoo would be good for power users that like tweaking their computer to the max(there are quite a few people that use live cds, discs that allow running the operating system off a cd and could allow the installation of it to the hard drive). Then, you have the hard core Linux users that use DSL(Damn Small Linux), which really is small; many people won't use it because of the name.
(Correct any of my statements that could be wrong. I was typing fast...)
