Like it! Have been trying for ages to teach my children to paint straight lines on the wallpaper. I must say, when you turn down the oxigen, the drawing becomes less!
I'm sorry to disappoint you, but HP tackled this problem already over 2 years ago. I own a HP Pavilion desktop PC wich has exactly the same thing. Two USB-slots at the back of the keyboard. This must explain why my productivity is so high ;-)
