I've ranted in the past about the move for TVs. It doesn't make sense for people (like me) who are space-constrained. I need to replace a 32" 4:3 TV, and could only fit a 27" 16:9 in its place. The "upgrade" forced me to have significantly less screen space.

I've seen the same thing is digital picture frames, which makes no sense whatsoever. Every real camera in the universe takes pictures in the 4:3 neighborhood, or even square in the case of larger format cameras. With a 16:9 frame, you're never, ever, going to use the left and right edges.
