to be honest, u know why is the only reason i tried linux. Becuz i was soooo obsessed with "tweaking" and "modifying" my desktop. I installed Window Blinds, Desktop X, Litestep, Cursor XP, Icon Pakager... and amazing wallpapers, only to have all this slow my computer down and make it extremely unstable.
one day, i came across, linux. and saw "kde screenshots" i was like NOOOOO way. if linux loooks that cool, im down. so downloaded the 3 ISO's..... and burned them and installed them. and i dont ever regret it. linux is like the best system there is so far. and best of all........ its 100% free.
but its true what vass0922 said. if you like challenges, and love to learn..... love to take things apart and put them back together. try linux. if you are more of a "hardcore" gamer using windows for "non-productive" reasons... the dont try it.
Linux is not for every-one!
