lickmygiggleThere is enough room for a full-size keyboard, a classic mousepad(I think~9x7) and an inch or two between them, depending on the brand of keyboard. You'd have more room with a smaller keyboard, obviously. Since it's completely flat, you could get a piece of 3/4' plexiglass and clear construction adhesive or 2-part epoxy. Have the plexi cut at the hardware store, in whatever size you need to add and glue that baby on there. It wont add any real weight and is completely customizable for my needs.
