The iPad mini has the iOS you know (and maybe even love). The only advertised accoutrement that Apple added to iOS 6 for the mini is a new algorithm that detects the difference between a finger resting on the screen and a touch that the mini is meant to respond to. Other than that, it's iOS 6.0.
Samsung, on the other hand, has decked out the Android 4.1 Jelly Bean running on Note II with loads of proprietary software. And for once, in an Android device, that's actually a good thing. S Note is the software that allows the Note II to recognize handwriting from the included S Pen. The S Pen has neat tricks like the ability to cut a user-defined image from a Web page and paste it elsewhere and draw on PowerPoint presentations, and it includes a customized email signature with an actual signature. It's a small detail, but don't we say that it's the little things that count?
