DSLRs are basically for hipsters and professions now compared to every typical consumer desiring them.
And? You are saying the same misinformed/underinformed pap that the prognosticators are doing. Single lens reflex cameras are actual instruments that allow the user some control over the images. Things you do not get in a smartphone camera. Small sensor are requires ultra short focal length lenses which in turn makes for images that look one way, even when fake zoomed. The limitations are so severe that some manufacturers make fake depth of field simulators that look like a Photoshop effect, not the dof circles of confusion effect (yep, it's called circles of confusion, and a difficult thing to imitate.
The smartphone camera is a wonderful replacement for the old 110 cameras that it replaced. And if it is good enough for you, that's fine. Some people like Toyota Corollas, some people like Corvettes.
Tablets will replace PCs for consumers. PCs will too go to hipsters and workstation users (power users).
These Hipsters you hate - stop obsessing about them - it makes you look jealous. Jes sayin'.
If anyone says a tablet can't--well, it powers my drone, which can fly autonomously on it too.... PCs can't really do that. Well it can, but in a very clumsy manner.
Sure. I fly my drone using either my Tablet or my phone. Good use for a tablet. The tablet at other times sits in the living room as something to browse the internet, or use as a remote control for my Television, or to play games on.
