Which version of Linux shall I use ?
Versions of Linux are, for example: linux-2.4.26, linux-2.6.7 and so on, see www.kernel.org for details 8D
And distros are very differ but all them are Linux Kernel distros. Use what your eyes like more, no real matter.

Anyway, Linux (any distro) is not as easy to explore for newbies as with _any_ Windows. On the other hand, if you spend as much time on learning Linux as you possibly done in Windows, you definitely get an improvement. Spend half a windows-spent time on its tweaking and you'll find a gold inside (;
Linux is worse in beginning but much better for everydays use 'in continuing', for power users.

If you are as far powerful as you know (and feel) what the Windows Registry is, you then could definitely be powerful with the /etc directory in the Linux topology as well.

Really, some people pick a 'free-of-charge' of it, some others choose freedom, someone likes its open source, someone finds its the most customizable... Linux is different, but is it you..?
