Digital Cameras
I noticed the newer generations of cameras have dropped the optical viewfinder to become more compact. I bet it is cheaper as well, and that is the main reason for the manufacturers. It is a shame, I use my optical viewfinder all the time. The reason is because it saves a ton of battery. I rarely ever have the screen on, which is what sucks up most power. Only leave it on for a couple seconds after taking the pic, to preview it. In fact, as long as you do not release the button, the image stays on for as long as you want, so you are in control.
The other observation I have is that all phone cameras in general suck. They are just terrible. Even if they come with a flash. After taking pics from the phone these past few months, whenever I go back to real digital camera, the quality seems amazing. I hope phones catch up soon, it's only a matter of time.
