well the first thing is install it
try a few , only you can decide it it is right for YOUR needs and likes
a lot of people like Linux Mint 14 for " new to linux" users
-- they do do a good job of making things a bit easier
--- disclaimer ---
i have NOT used this so....
but it has some very good reviews
different distros are targeted at different user market
RHEL( not free ) or CentOS ( a free rebuild of RHEL )
is targeted at the server room and the office ( NOT home use )
SUSE enterprise Linux ( not free )
the server and the office
OpenSUSE 12.2 or 12.3
a bit bloated and NEEDS a computer with a LOT of " horse power "
4 to 8 gig ram and a i5 or i7 CPU
But good for home use -- and the new user that REALLY wants to learn something new .
Fedora 18 ( soon to be 19 )
not so good for the "New user" unless they really LIKE to tinker and fix things
PS. it is a "research and development " distro .
try a few
try a few different "Desktop Environments "
KDE4 , Gnome 3, or gnome 2 if using fuduntu or CentOS , xfce,...
find out what you like
have a look at " Distrowatch"
( warning "Arch Linux" is NOT new user friendly )
