The rear finger print sensor has already been done, just as the finger print scanner had already been done before by Motorola before it was featured on the iPhone. I don't think Apple has done anything innovative in years.
Oddly, Apple did not invent the computer, the portable music player, wireless networking, the cell phone, nonlinear video editing, web browsing, or integrated circuits, but they've done very well for us with those things.
Despite the general griping around here, I doubt many people wish they'd never bothered buying Apple products. I've owned close to twenty of their computers going back to the Carter administration. Most of them still work, and I find them all enjoyable in one way or another. I've also had three or four Newtons (wish I still had the 2100), half a dozen iPhones (all of them still work), and more accessories than I can remember. Out of all that I've had a tiny list of failures: the print head broke off my Silentype, my 3rd gen iPod died, and my very first Apple II (power supply, hard drive motor controller, and one ROM). Everything else still works.
In your statement I quoted above, it really looks like what you're saying is "Apple can't be right unless they're first and everyone else follows suit", maybe with a little "Not created here" attitude to salt that dish. I had that attitude. I used to look at everything Apple created as the only possible path. If Apple had stuck to that, we'd be blazing along on Geoport modems that finally achieved 128kbps via a firmware update that was 18 years overdue, on machines running a 7th gen PPC using ADB keyboards and mice, browsing with the 95th version of Cyberdog. Eventually I realized that Apple can't invent everything.
So, I really don't care if Apple "innovates" anymore. (That word reminds me of 1990's-era Microsoft begging the feds to leave them alone otherwise they wouldn't be able to "innovate", which according to the MS dictionary means "ruin other companies if you can't buy them or get away with copying their products".) What I need - and I'm guessing every other customer out there needs - is for Apple to get it right. Do what people want, better than any other company. Give us the tools to communicate and create, and make them easy to use and beautiful to look at.
