"All of this (admittedly wild; sorry, coffee is kicking in) speculation definitely has me excited for the future of Apple, though! I haven't felt like that since Steve was around."
Wacky. Your vision of shutting out unsigned apps has me looking for the exits. I've been an Apple user since the 80s and I'm pretty sure this would finally make me jump ship. Apple's current Big Brother trajectory frightens me to no end.
I'm pretty sure this won't change your mind, but my view is more-or-less "better the devil I know." Trading in Microsoft and Adobe's phone-homers for Apple's is fine in my book.
I don't use Microsoft or Adobe software as it stands. Getting rid of a couple of third-party updaters I don't even use in exchange for giving Apple complete control over whether or not I'm allowed to run something is an awful tradeoff. It's just barely tolerable on iOS because I use those devices more as appliances than computers, but it's not workable for me on a real computer.
