And it isn't as good of a camera as a modern dedicated camera is. In fact, it might not even be as good as the camera you replaced it with, especially when it comes to ergonomics. Similarly, a dedicated gaming device often has better ergonomics for gaming than trying to play the same games on a phone.
I understand convergence. I understand satisficing. I also understand why people still make SLRs, and it isn't just to keep dust out of the various lenses. If you really want a good camera, you aren't going to be fully satisfied with a phone that has a megapixel count. The gaming world is more fluid because games themselves can adapt to new hardware and interface styles, but specific games often really do go better when you have buttons as opposed to a touch screen.

And, finally, my little quirk: I refuse to believe that decluttering is a valid end in itself. Having a closet full of stuff I enjoy owning isn't a personal failing or a personality flaw.
