Good insights. Apple didn't spend too much R&D money on its own innovation. It integrated all the great technologies together and produced a few best selling products. Can you please reveal what the following technologies are coming from? - Tablet (Palm Pilot?) - Touch screen (HTC?) - Battery - Nano PCB technology It's hard to believe the touch screen technology is suddenly improved and Apple used it for its success almost for free. In 2009, I was busy bidding touch screens on eBay, which were so dumb and expensive. Suddenly, everybody has one in hand. Magic! The question is why those companies that created the technologies didn't profit that much? At least Apple's R&D expense should be sky-rocketing compared with the previous years when iPod touch and iPhone being released even if they didn't created the technologies.
