Apple gave credit where credit is due when it comes to the inventor of the idea for music players like the iPod. Apple used Kane Kramer in a lawsuit when they needed to prove who held the acknowledgment of iPod invention. When Kane Kramer was just 23 years of age in 1979, he created the IXI. The credit card sized device held 3.5 minutes of music on its internal chipset, which is pretty impressive given the technology of the day. Kane did envision that capacity would grow with time and he certainly had it right. He did try and capitalize on the idea, but that fell thru given the timing of the device.
Kane was compensated for his time when he was helping Apple in their trial, but he has yet to receive money for the iPod itself. Hopefully Apple helps him out a little as we know it would barely touch their wallet.
