I use a variety of Apple keyboards, an IBM Model M (wonderful original PS2 model), and an IBM ThinkPad keyboard, depending on which machine I'm using at any given time. All excellent, especially with the Caps Lock key set to Control. All non-Apple and non-ThinkPad laptop keyboards I've seen are horrific, as are all cheap "included with hardware" keyboards from Dell and the like. Stay far away. PS: Heed the advice above about keeping your wrists straight as you type. Avoid the mouse "flick," where you move your right hand to the mouse on the right (left) of your keyboard and thus flex your wrist slightly to the right (left). In addition, try ordinary and reverse wrist curls with very light dumbbells (<20 lbs each), and do them regularly. Will do wonders to keep RSI at bay.
