Here's a nifty laptop stand called the Oyster which brings the monitor of your laptop up to eye level, easing the strain on your neck and shoulders. I think that this photo how it works. It requires an external keyboard and mouse, but I think it'd be well worthwhile if a laptop was my primary work station.

Here's another stand with this configuration. None of the dealers seem to list prices for this, though... hopefully it's less than the $179 amazon is asking for the oyster.
