Mine says 1.3 GB on my iPad mini Retina and 957 MB on my iPhone 5.

I'm passing on this update for now. I want to see all the repercussions first. Besides, there really wasn't anything in the list of new stuff that excited me. The new keyboard looks like just another autocorrect POS I don't want to deal with. A keyboard where I don't have to jump back and forth a dozen times between numbers, symbols, and letters just to enter a password or email address would be nice. Fat chance of getting one though.
