You should also appreciate the enhanced lift action of the new top (screen) half. The older models aren't bad in this department, but the protos of the new model i've played with at work feature some nice efinements that makes lifting the screen so much better feeling. Hard to describe - just easy and smooth with no resistance when compared to other generations. As I've mentioned before (I think) the enclosure is also better physically engineered - the top half of the keyboard part has a much nicer internal latching mechanism to hold it all together - this isn't something you'll see, but should play out with increased longevity of the unit proper.
