I really think HTC did themselves a disservice with Boomsound and the "Ultrapixel" experiment. The Boomsound sounds great, but takes up a lot of space on the front of the phone that could be used to fit more screen. How often does one really sit and watch a video or listen to music without headphones in. Maybe I'm in the minority, but I rarely do. I'd rather have more screen and less speaker.
The Ultrapixel camera is also shoddy. It takes decent enough pics, but zoom in or crop it and the quality gets degraded due to the lack of megapixels. I know megapixels aren't everything, but a decent camera needs more than only 4. The whole lowlight picture thing is overblown.
