I keep insisting that the most important function should be the ability to freeze a screen on lcd side and transfer it to e-ink. this is very easy to implement, alexreader android machine with 2 screens already has this. then you can open a pdf in any android pdf reader, or open any page, press and hold rotate button and select transfer to eink. job done. you can read your pdf in landscape mode, or transfer any web page from any browser to e ink. I can not believe entourage people did not think about this.
