Really don't know why so many people have problems with the Dash!
It cruises fast (only a couple of minutes behind a jet on most UK/close Europe sectors), climbs quickly, is economical, is not too noisy (when the NVS is working) and is reasonably comfortable (I prefer the 2+2 layout dictated by the narrow fuselage).
Fair to say that there are a lot of regional/hub feed and point-to-point sectors around the world that wouldn't be operating if it didn't exist.
