With the signature service/seating arrangement though, you don't get the same number of seats that an Airtran 717 has (correct me if I'm wrong).
As far as it being a pile of *rap or not -- I'll say the same thing that people have said about the 328 Jet for such a long time - people cuss and swear that it's the velcro jet, doorknob, dorkjet, slower than molasses, etc etc etc...of all the regional jets, though, it's probably the most comfortable one to ride in back. And that, my friend, is what the people care about.
Now, if you're going to knock the 170 on reliability/dispatch issues, that's an entirely different story!
Take care,
