Ah, having trouble with satire, are we? No need to be defensive!
You posted such an over the top, silly, sweeping statement, I figured it would be best to reply with gentle satire rather than blunt refutation.
You wrote this:

fitshaced: "Zoom on smart phones is pointless unless it is mounted to something to keep it stable."
I could have responded like this:
"pointless"? Really?! Millions of people use the zoom on their Samsungs, iPhones, and other smartphones every day *without* the need for a tripod at all! They've produced thousands of great *handheld* zoomed photos! That's even easier to do now with the addition of optical stabilization.
Instead, I replied in mocking fun:
In fact,
"Cameras on smartphones are pointless unless they are DSLRs"!
"I mean, who's ever going to use a camera on their phone?!"
And, of course, you are right! No one ever uses the zoom on their smartphone's camera. Never seen it done. Why? Because it's completely "pointless"!

------------------------------------
The Big Grin there at the end was the tip-off that this was satire and the quotes wildly offbase-- and, just as ridiculous as your own!
Maybe the direct response would have been better and sunk in more! 
In any event, to reiterate, *handheld* zooming on smartphones is hardly "pointless".
