It's a matter of taste, as evidenced by the success of both eInk and LCD devices on the market. For me personally, I think the improved readability is well beyond superfluous: I regularly bring my Kindle to the beach and read in direct sunlight, a feat that's not possible with other display tech right now. Plus I can bring an eInk device with me on holiday and not worry about charging it or even packing a charger is a win in convenience. Someone pinch me when PixelQi becomes mainstream, or Samsung does something with their Liquavista purchase, or maybe when Mirasol shows up in the market.
