Pretty much MacRumors and Daring Fireball for me. I'll glance at AppleInsider once a week or so, especially during the build-up to something big. I
can't stand The Verge, Engadget or Gizmodo...the three-headed Ground Zero for first-world hipster douchenozzlery, IMO.
I know Gruber can work a person's nerves (including mine), and he can be the most off-putting dickhead east of the Rockies...but I'll put his record (on accuracy, "little bird" tidbits/leaks, opinions on matters of tech and generally Being Right when it comes to Apple over anyone. The guy doesn't have a side business of printing retractions and/or corrections like some other sites I could point out.
If Gruber (or Jim Dalrymple) says something is true, or coming, I start eyeing my bank balance and making some plans...
These other places? I can't find a grain of salt big enough.
