There is a reason I didn't mention it, and that is because I found the seat reasonably comfortable (I wouldn't want to go long haul in it, but for an hour each way it was more than adequate - and I'm 6'3" and not exactly slim!), and I didn't find the noise that bad. I have been in far noisier aircraft, and I would nominate the Dash-8 and the ATR as both being way noisier.
I used to fly a lot on the early ones (when they were in BA colours), these seemed much newer (-JY and -JP). Have never noticed any funny smells...
