I've had mine for about two weeks. The extra screen real space is nice if you run at the 'looks like' 1920x1200 resolution. The downside is the integrated graphics can seem borderline for driving the display at times. Some apps have issues. Fullscreen flash video is choppy in Chrome though works fine from both FF and Safari. The fans are dead quiet at low RPM, so if you run on integrated graphics with low cpu use (editing text, web browsing w/o flash heavy sites) you will hear nothing. On dedicated graphics and moderate cpu (flash video), it gets warm/hot and you'll hear the fans, but it is not bad. At high cpu use system can be really loud. I think I'm going to return it and wait for the next rev. PS. I also have a 2008 MacBook Pro. It was running hot and loud until I blew it out good with a can of compressed air. Now nice and quiet.
