Sounds about right. I'm wondering if the raised chrome has got something to do with audio circuitry, or it would be flatter. A switch to AMOLED could eliminate some thickness represented by backlight panels, or migrate part of the circuitry to back of upper screen. Thinking also about how to make screens ~10% bigger, for 20-25% extra surface area.
A new version should be dual-core with higher specs across the board. More work on upper plate/hinge. I would pay the premium for more exotic alloy in the hull. Big questions are power and cooling, the Imerj prototype didn't really solve either. Ideally you'd want graphics clock to change with open/close, a 40% drop in speed saves 5-10% power in games and greatly reduces heat buildup.
Not sure how I feel about gimmick features like (fake) "4G" that drains battery for minimal benefit, or ultra camera. With enough hardware power, an external display could be nice...
