what is the best linux to use for me thats easy?
There are many major distributions of Linux that are easy to use and if you are coming from Windows XP or Vista, you will find many things familiar. The *Ubuntu block is typically where most people begin with Linux; each version of it has, at its core, a different block of programs that generate the user interface. The most widely used are Ubuntu, Kubuntu, and Xubuntu.
Ubuntu is built upon the ideas and software framework of
Debian Linux, in which the first and foremost idea is that an operating system should be free and that its programs should be open source, therefore allowing anyone to work on them, not just the developers of the program, that the entire community of users should be responsible for generating the programs that they use. Ubuntu uses the GNOME GUI, which is designed with usability in mind and creates an environment that tries to give the user the most control over what their usage experience is like -- within reason; some Linux distributions allow for nearly unlimited customization at the expense of ease of use for the average person.
Kubuntu is a derivative of Ubuntu which uses the KDE GUI. Here the focus is still on customization, but first and foremost aims to give the user a unified suite of programs by which to operate similar to Windows or the Mac OS. Proponents of KDE, such as myself, often cite the "patchwork" appearance of GNOME stemming from a lack of a unified development team that makes programs flow together with one another. In my opinion, KDE is the easiest GUI by which to transfer from Windows to Linux. In addition to the core programs, the same huge amount of open source programs available to Ubuntu users is available here.
Xubuntu is based on the GNOME GUI and many visual elements will be very familiar if you are used to using Ubuntu or another GNOME-based distribution. The goal of Xubuntu, which uses the XFCE GUI, is to make the operating system as efficient as possible in regards to system resources while still keeping the same usability that GNOME offers. It stands to reason this is one of the best operating systems to use on older PCs such as those containing a Pentium 3 or 4 processor. A more extreme distribution in this regard is
Damn Small Linux, which goes further and strips out extra features and usability elements in an effort to continue to reduce system resource overhead.
Either of the first two are a great place to start your Linux experience and are shockingly easy to install; the instructions can be found on their respective websites. If you are running a slow computer then you might consider Xubuntu instead.
