Agree the camera can be poor but I think future software fixes will remedy that. Hardware upgrades to Nexus 6 are more affordable due to lower price of the device, too. I also like the extra features like multiple panoramic options and photo sphere.
Skeptical about software fixes for camera problems. If the hardware itself isn't very good, then software will only be able to do so much...
Poor camera is not a software problem. It's a matter of hardware. And skimping on the qualitative stuff like a camera is a very easy way to lower price.
