Ergonomics

After posting my treadmill desk pictures on the Office Walkers site, I noticed several posts indicating that it would be best to have a monitor that is separate from your computer (particularly if you are using a laptop) so that your screen is at the appropriate ergonomic eye level.  So adjusted my shelf boards a bit so that my laptop is on a shelf clamped to the top of my treadmill.  I hooked up a spare wireless keyboard that I had lying around and it rests on the lower shelf.  So far, so good -- no neck pain, eye strain, or anything else.  I still need to create a better place for my mouse to rest.  The keyboard is on a bit of an incline, which works great -- but I think I need a more level surface for my mouse.
