re: I don't think you get e-ink, Chris
"e-ink isn't like a LCD screen. e-ink displays are of higher DPI than most printed books, so they're hardly going to enrich optimetrists - the opposite, if anything."
Please go back and read the article. The article (and my comment) was not about e-ink, it was about e-books. There *IS* a difference. Specifically, please note the first sentence of the second paragraph:
"The cash acquisition comes just days after Amazon extended its Kindle e-book store to support the iPhone and iPod Touch for US customers."
That kind of kills your reliance on e-ink, don't you think? That is, unless you're saying that the iPhone and iPod Touch use e-ink for their displays.
"While some providers charge high and use DRM, others like Baen completely eschew DRM, and their books are typically $5-$6, far less than the £6-7 which is charged for paperbacks in the UK."
So because (at least) one supplier sells their e-books for less than the physical product, that means I cannot make a statement about future prices (or the average price in general)? Well, in that case, Fat Wreck sells their CDs for $12.99 and under, so I guess I can't ever mention that most CDs are commonly sold at prices up to $18.99 or even $21.99 now.
