The Nexus 7: Google ships a tablet

Sorry, I just don't agree with your blanket statement, I'm fine with accepting that for most people it's like you say but definitely not for all because I find reading on certain e-readers unpleasant. To me it's like reading those paperback that use recycled paper that is SO gray that it loses the contrast with the black text. So it depends a bit on which brand of e-ink display is being used.
