Seems desperate, only "covering" their bums
With Microsoft 1-upping the smart cover with built in keyboard and touch pad, of course Apple has to follow suit by at least releasing patents to avoid competitors building more competitive functionality into a tablet cover.
I doubt Apple will implement any of this as it seems very desperate. Why do I need a secondary display on a tablet cover when the tablet screen is just right there. Are we so lazy a society that I can't flip open a tablet cover.
Why offer touch features that isn't a keyboard when the whole point of a tablet is to provide a touch display. Also I doubt Apple would want to make their iPad appear like a glorified solar calculator by having solar panel cover.
Also I think Microsoft pretty much has this concept patented when they came out with their "auxiliary screen" concept back when Windows XP came out, all laptops were going to offer a second screen on the cover for quick lookup of information and status.
This completely goes against Apple's comment about mashing together disparate devices, like a PC/Tablet combo. This seems like Apple wants to mash a toaster with a slightly different type of toaster as I don't see any reason to combine a tablet with a display and touch with a cover with a display and touch.
This seems to be Apple's biggest competitive move, swallow up as many similar patents as possible and then sue the crap out of anybody actually coming out with a feature that uses it. Apple has more patents in reserve then products, they are becoming one of the biggest patent trolls on the planet.
Apple should just simply feel secure about the quality of their devices and the "zen-like" simplicity of their designs, and leave the conglomeration of devices and features to companies like Microsoft and Google. They really don't have to resort to patenting garbage ideas for the same of staving of mythical competition.
