I was all ready to buy an HTC M9 until I saw the performance, heat, and camera reviews. The camera was the nail in the coffin, as I needed a high MP camera that could at least tie or beat an iPhone (not a terribly high bar, except that 8MP gives them an edge for low-light).
The G6 was already dead to me due to dropping the microSD card (yes, I frequently shoot 1GB 1080p60 video with it when my camcorder isn't handy) and I store a LOT of pictures on it. A non-unlimited data plan makes local storage a MUST.
I'm holding out hope for the LG G4, since it's supposed (rumored) to have a microSD slot and a new camera (16MP with F/1.8). The 1440p screen is a nice toss-in, but the Snapdragon 810 could make it a tough (but acceptable) sell. At this point, phones may be circling the drain until Samsung releases the Note 5 or another "alpha" phone that keeps the microSD card slot.
Yes, there's always an iPhone (if you ignore the microSD slot issue), but if we were considering an iPhone, my problem would be solved since I'd have no options anyway. 😛
