I am experiencing the wifi sync issues quite heavily. My iPhone 5 might sync 1 out of 5 times, probably less.

I wouldn't say that iTunes is as bad as he says, since it's not crashing very often for me when using it normally. But every single time I plug in and iOS device it hangs, for up to 30 seconds, and at the end it either crashes completely or recovers. Note that this only started happening on iTunes 11.

I've had issues synching with the cable, iTunes telling me it just can't sync right now.

At one point, I plugged my phone in to sync it since it wouldn't over wifi. Except this time iTunes decided to re-synch ALL my music (over 4000 songs).

The App Store constantly harasses me to update the Twitter app, that I have deleted over a year ago.

I am on a late 2010 macbook air with 4GB of RAM, and I don't believe I have done something to my computer, like you say. It is working perfectly otherwise.

So you are saying that crashing not very often and delays that don't exceed 30 seconds are the signs of quality? I have around 40000 songs, this is why we have a different experience I guess. Each time I force-quit iTunes, I have to wait around 7 minutes for it to check the library when starting again.
