I got my Carrara7Pro during the "Buy 7Pro now, and get 8Pro later" sale. Haven't installed 8Pro yet 'cause I've heard about a lot of bugs that may be show-stoppers for production flow, and I have a big project coming together now. Thought I'd wait for the bigger bugs to shake out, and I'm also putting together a new 64-bit system. 7.2Pro has run smoother, stabler, and faster than 6, so I'm in no hurry.
