Apart from the display latency this looks great.

What would be sweet but would never happen because most consumers don't need it would be a screen that can switch between normal LCD and a B/W eInk. That or the day of colour eInk arrives.

I don't think it is eink but take a look at Pixel Qi screens http://www.pixelqi.com/

This is going to make programming in outside, strongly sun-lit environments a breeze :)
