I used to work for a company that occasionally had to interact with others' Lotus Notes setups. At one point, there was some discussion about migrating one of our systems to a document store. There was a fair bit of back-and-forth at first. After someone pointed out that Lotus Notes is basically a document store, though, the idea was dropped more-or-less immediately and unanimously.
