As of iOS 5 or 6, iOS-based devices became first class citizens; i.e., they no longer required a host computer to be registered or to download content from ITMS.
You don't have to register the card.
I don't know but audio and video encoding/decoding are handled by specialized chips in most mobile devices the way GPUs handle graphics on desktop computers.
In the context of the above answer, application software is going to follow the hardware's capacity.
Someone who has iTunes installed on a desktop computer and syncs with their device has automatic backup. Remember that iOS devices aren't registered as USB Mass Storage devices so plugging one into a computer does not result in the device appearing on your desktop with an exposed filesystem, and even if they did the filesystem is not guaranteed to contain a single package for you to back up.
The storage is shared. iOS takes up as much space as its developers deem necessary, and the iOS 8 update irritated a number of device owners whose storage wasn't large enough to accommodate both the update and their existing installed apps.
The firmware in iOS-based devices and Apple branded computers contain an anti-theft feature where the device can be registered with iCloud to a specific Apple ID. When this is done, the devices/computers periodically phone home when there's an active data connection and if the Apple server has the device's serial number listed as stolen, the device prompts for a (user-set) unlock code; after a limited number of failures, the device actually bricks its own firmware making it useless. One of the dirtiest scams being run is selling a used Mac laptop at deep discount, then when the purchaser later gets prompted for this unlock, the previous owner charges an exorbitant price to furnish it.
Once you correctly log out of iTMS on your device, the user settings are gone. Also, you can make the device reset to factory settings. If you've registered your device with iCloud for antitheft, you will have to deactivate this at iCloud's website.
No, and I wouldn't hold my breath waiting for one. There are genuine limits on what a tablet can be expected to do compared to a desktop computer, no matter what startup CEOs say to get press coverage. ARM architecture was specifically designed to be low power consuming, not powerful and just as PNG didn't aim to replace JPEG, ARM doesn't aim to compete with desktop CPUs. Your desktop computer can render graphics competently and encode/decode multimedia using nothing more than CPU without slagging the OS; a mobile device depends very strongly on being able to pass off those number crunching tasks to specialized hardware and without it would be about as sophisticated as a Nintendo DS (which itself requires two ARMs to handle processing, I/O, video/audio and 3D rendering simultaneously).
