FINAL??? you mean you don't intend to change your desktop???
I change my wallpaper about once a month, it gets old after a while I change the icons whenever, specially if I find one I really like or I decide to make one (it's easy)
My desktop is a constantly evolving place, it just depends on my mood
Well jm if its too much of a strain on your rickety ol body - start using desktop themes and set up windows to rotate them monthly, that way you'll avoid any medical side effects
