I live and work in Cambridge and one of the new separated lanes is on my regular route to work. The design, I think has been mostly an improvement, with quibbles. There's definitely less chance of getting doored, but I don't like that the lanes go right through bus stops. Also, cars turning at intersections don't see you on the other side of parked cars. A big plus, though is that the city actually keeps the lane cleared in winter. The regular bike lanes get to be pretty bad and blocked by parked cars when there's a lot of snow.
