I will upgrade. I bought my Macbook Pro after June 11 so I am eligible for the free upgrade.

I'm only upgrading to make use of dictation. I want to be able to yell at my Mac and tell if where to dodge/burn on an image . The neighbours will be kept awake to screams of, "Not there you idiot! Over theeeeeeere!!!" as I point violently at the screen

In all honesty, I have read reports of improved stability. I've had a few occasions where Aperture and Final Cut Pro X have hung and I've had to reboot - so it would be nice if that goes away (even though it boots in 15secs). I also like the idea of Power Nap, particularly when downloading large files or running updates overnight.

Thought it would be on the apple site by now but it appears not yet...
