I would agree with you.
Also, simplicity of install. No need for lenses, sleds, processors, etc.
You can check out my theater below, but I decided to go with CIW for many of the same reasons as you... in addition, I watch a fair number of concert blu rays and they are almost all 16:9. Also, I like the expanded view of IMAX etc.
I ended up going with a AT 16:9 screen that is basically the entire width of my room, so the 2.35 image is as big as it physically can be...
