Valid point. However, I typically don't find it an issue unless you are running the -exec on 10K files. If it takes 0.1 second with xargs and 1 second with -exec (which is 10 times as long), I don't see it is worth arguing about. However, it is **definately** worth mentioning and I have made a note to add it to my Linux Tutorial.
