I've seen and used the beta for OSX. It's got a ways to go before it makes it to "production" status. If they can iron out the bugs and speed it up before Jan. MacWorld......it'll be nothing short of a miracle. It sure is pretty though
The new "browse" feature is really cool. It allows you to scan folders and view all thumbnails instead of clicking on a file to see a thumbnail.
Still playing around with it.....
