Actually, it's exceptionally good, although the planes are getting old and there have been some more high-profile cock-ups in the past years.
I've heard the sync problem before on them... it can be pretty nasty.
What I kind of wonder about is...are there ever going to be new, better plane designs in the rough size class of the MD80/xx, the A300s, and the 737? I mean, more than light refreshes? It seems like now both Boeing and Airbus are talking a lot about gigantic flying casino boats now.... but the reality is that most of us spend most of our time flying in these smaller planes.
The Embraer E-190 is a close competitor and I think a couple US airlines are starting to fly those. They're bigger than a regional jet but a bit smaller than a 737. That's really about it though.
