Whether it's for professional use, or for a 5-year-old kid, the keyboard should be as advertised. The 2000 is not, and never has been. When I complained about the OS not being in Flash Rom, they directed me to the disclaimer line that said something like "all specifications subject to change".
Can you just see Ford Motor Co. telling someone, "Of course we advertised it as having a transmission, but all specifications are subject to change."
