Ice cream and condoms didn't exist in the ancestral environment; using them as criticism of evolution is like using a screwdriver to pound nails and then blaming it for being a poorly designed hammer.

The backward retina may be an interesting case in point here: I've seen an article (years ago, don't remember the link) claiming it makes maintenance easier; an important advantage if so, considering that unlike your cell phone camera, this is a piece of hardware that has to operate without replacement for a timescale on the order of a century. I don't know whether it's a good trade-off on balance, but even if it's not the optimal design, it might still make the retina a relevant example of something that actually makes more sense than it would seem at first glance.
