If the main appeal is the FLIR sensor, you can get that as an add-on for an Android or iPhone. But this phone is obviously useful for more than that. The waterproofing alone would appeal to a lot of people.
I was seriously considering this phone.

[li]Rugged/ dropable[/li][li]Bigger/thicker (phones w/of a case are too thin IMO)[/li][li]FLIR - I’ve played with an add-on one to a friend’s ipad before. That one is a joint with the camera, giving the details of a regular photo with the added heat colorization of the IR; very cool![/li][/ul]
However it’s priced like a premium phone @ $600 & depending upon your phone you can get this add-on FLIR & still save money.
I was waiting for the Pixel but don’t think it’s all that at that price. I’m probably getting a Nexus 5X but this is my second choice as of right now.
One thing to note is that the FLIR camera has a resolution of something like 160 x 120. They do some clever blending with a regular camera image to produce something recognizable. It’s still pretty useful, but it’s not exactly HD quality.
