The BOTTOM LINE in the corporate world is profits. Whatever they can get away with to drive up profit & sales, they'll do. It's up to us the consumer to determine whether it's worth it (to us) to UPGRADE to the next model (yet) or not. Hardware & software Manufacters are banking their products on built in obsolescence. Only when sales drop will the keyboard manufacters only bring out new models when significant feature advancements are made. Power to the people. We drive the market. - Scott
