CMOS image sensors have very much caught up to CCDs in image quality, have a significant power advantage and support higher frame rates. This might explain why CCD use in high-end digital SLRs will be moving from 12% today to 1% by 2014.
I'm not sure that CMOS has the big cost advantage that one might assume. CMOS image sensors aren't built in standard logic processes, where huge volume means low cost.
I totally agree, goafrit. It's another case of volume trumping quality as it is in other consumer electronics devices. Yet astronomy requires CCD quality: http://22.214.171.124:8080/CE2release/cesMain.jsp

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
