It will likely stay in "good condition" for ten years if it is not dropped, squashed, touched, used, etc., but is that what you really want your notebook to be doing all day?

It is likely the notebook will become obsolete in three years. The LCD should last about five or six under normal to heavy use. It's a tool; use it.
