that is a good idea!, have them pop out of the side or top, you want to view a video or play music only your not using the keyboard, and make a slide switch that operates the speakers movement and same time powers AMP and connects jack-detect so all audio goes through AMP, line out in headphones still possible at the same time if needed....

was also thinking about having them bulge out where the top of the screen is so your hands have a ridge to rest up on

very crude drawing, think rounder corners
