iOS 6 introduces the following features:
Windows 8 is built on the Windows 7 backbone, so it will run programs designed for regular windows even though it is a touch-screen centric interface. at any time in Win8, the user can switch out of the touch-friendly mode and back into the normal desktop. Win 8 is a full blown operating system designed for either desktops or mobile computing with all the robustness and customizabilty of a full copy of windows. iOS, on the other hand, is designed exclusively for phones and tablets. it is more limited in what it can do and run. iOS is designed to run smaller apps rather than running full programs. iOS can not be customized or changed the way that Win7 or OSX can, nor can it run programs that either of those two oprating systems can.
iOS 6 is free.
Yes, when iOS 6 comes out it will be free of charge, just like iOS 5 and iOS 4 were.
Some ios 6 devices can be jailbroken.
Probably not. The only OS for iPhone currently in beta is iOS 6. There are is no iOS 5.1.2 currently in beta and iOS 6 should be out within a few weeks. Unless a security hole in the current iPhone OS is found before 6 is released, don't expect an update to iOS 5.
Yes you can.
No. It is just to soon for the devs to get an untethered jailbreak for iOS 6. Plus iOS 6 isn't available to the public just yet.
Yes. All iPad minis should be running iOS 6 and can update to iOS 7 this fall.
