While the split keyboard may be more restful to the wrists, the touchpad is extremely awkward to use. The clicker has been moved from below the touchpad to the left of it. Since I usually use my right hand on the touchpad of my Powerbook, that means I either need to squinch my hand all the way over to the left to use the clicker -- which is difficult and painful -- or tap the keyboard to "click" the mouse; which is fine until you need to "click and hold down." I'm sending this back if I can.
