This is a key point: the iPad's display is only going to get better over time, while e-Ink displays are probably not going to improve much from here. They might get faster, but what else is likely to change? I can't imagine investing in a company that spends time optimizing an e-Ink display. It would be like building a better vacuum tube. When the iPad gets the so-called 'retina display' from the iPhone 4 model, it's all over.
