What was the point of Apple waiting so long to release their tablet if it wasn't even to include the e-ink-killer Pixel Qi 3Qi screen?
Pixel Qi 3Qi
has been confirmed to be in production now, so that should mean several competitors will be implementing it in cheaper Netbook/Tablet convertibles and the Apple iPad will look quite weak in comparison.
Not only in terms of readability, sunlight readability, also in terms of battery life, an ARM Powered product like the iPad could most surely achieve upwards 50 hours battery life with the Pixel Qi 3Qi screen in reflective mode since the LCD backlight is surely the single most power consuming component of the whole iPad.
