Hey all, I have a MacBook 2GHz Core 2 Duo. I'm thinking of taking the plunge to iLife 11 (from 9) now calendars are back in iPhoto. Anyone have experience of it on older machines? Is it quicker or slower? Is it bloated or sexy streamline? Oh, and a vaguely related question: is the new iMovie a satisfying experience (function-wise as well as speed-wise)?
