I just got a 1912 and I absolutely love the networking features. The only reason i got it over the 1712 was that they were the same price at Crutchfield so I went ahead and got the higher end model even though it has a lesser version of Audyssey on it. Coming from an older AVR that didn't have Audyssey at all I can say the sound improvement is huge and like I said, I love the networking. I haven't messed with airplay but I've been using the internet radio and pandora alot and I also like the ability to control the receiver from my android phone. Once I figure out how to use the media servers on my computer I'll be in heaven.
