Note 5 Disappointment

Hardware specs
Samsung Exynos 7 octa-core processor
32GB/64GB storage options 4GB of RAM
3,000mAh battery (non-removable)
No microSD expansion slot
Wi-Fi: 802.11 a/b/g/n/ac
No usb-c

My only question is WHY?

Why smaller non-removable battery?
Why no microSD?
Why no usb-c?

Why not just keep my Note 4?
