Yeah, but ...
Do you use your laptop all the time?
Get yourself a laptop desk, seriously. I don't know what he is talking about, but I suggest one of those wood topped, beanbag-padded underneath, takes up about the same space as a large pillow, puts all your joints in a better position that you can control and alter as you need, laptop desks for about forty bucks. It would be a semi-permanent homebased accessory to your laptop that would also be easy to move when the time comes.
