There are many application-specific scenarios that are enabled by RX that would still take quite a bit of hand-rolling a deep knowledge of RX to get right. A favorite of mine right now is https://github.com/RolandPheasant/DynamicData https://github.com/RolandPheasant/DynamicData which I use for easily "deriving" from in-memory collections to create new collections that are actually "live views" onto the source collection. Makes things like mapping, sorting, filtering, paging, and so on super-simple while letting you avoid creating unnecessary state.
