I never said I supported, or even needed, 8-core processors. The 'power user' I refer to is aka 'a road warrior' -- maybe a traveling sales person or other mobile professional. Someone who actually uses the hell out of the phone's features to get things done and is not always conveniently located next to a power source. These kinds of people kill batteries & can't schedule their day around access to power outlets. They are dead in the water if they can't swap out the phone's battery (at least Samsung understands this). These folks are likely also in need of hot-swappable storage (Samsungs understands this, too.)
Hopefully that answers your question.
Personally, I shoot a lot of photos, record meetings & conferences, and shoot video for work. I would not be able to do all these things if I was restricted to internal memory - especially not a mere 16GB.
If storage and battery life are not important to most of you guys, just remember that you do not represent every one of us. I see a lot of people complacently accepting limited capabilities in newer phones with little thought about how much they are actually losing out on.
