Except for those cases where you want counts, only unique/only duplicate, skipping fields, doing case-insensitive duplicate detection, or only comparing a chunk of the line - all but the last two I've used and now that I've found those in the man page (GNU uniq) I can replace some silly shell hacks that I've used over the years. It's like saying that tail is pointless unless you're doing tail -f... you're missing the actual useful functionality due to presuming the tool only does what you've done with it in the past.
