The move to Premiere so far has been extremely quick. I was not only able to set my layout up to almost exactly mirror my final cut layout, but all of my keyboard shortcuts work the same.
Moving projects from FCP required just a simple XML export. Everything came in just fine, and I was cutting within 10 minutes.
The cool thing about premiere is not only do all my FCP skills translate directly, but I no longer have to transcode source material to ProRes first; I can drop media into the timeline directly, as is.
Loving it so far..
