I'll stick to eInk for reading. I tend to stare at LCDs whole days and frankly I get tired of it.
As for eInk over LCD...
eInk is perfect for reading for me. It means I don't have to strain my eyes(yes I actually notice when I'm doing so on an LCD). This is one of the reasons I tend to rest my eyes on the keyboard while typing even though I'm perfectly capable of touch typing.

But this still looks like a nice mobile device for general use. I don't expect my devices to do everything and I'm dying for an eInk cell phone. I know there's a Motorola F3 might even get it but I doubt it.
As for using LCD for reading I tried this a few times. Took about 5 minutes then I couldn't stand it anymore. Doing things on the LCD vs reading are two completly different things.
Anyway great device but I'll wait for the
