So except few things i have no that "cheap plastic" feeling, i mean it is not made for fulfilling the plan, and whenever i worked in windows (especially with Vista and 7 -when i am forced working with them) or kubuntu i have that feeling.
So my suggestions (based on my experiences with Salix OS 13.0):
1) Don`t force lames (like me

2)Some application like file manager or torrent client have more transparent version, actually i have "that" feeling when i use them.
You must too much search when you are Linux newbie like me , the "where i saw that? crap i lost it" syndrome may appear when a newbie working on/in it.
Maybe that is all.
