I see nothing wrong with it. . .
The point is, for FOCUSED reading, as mentioned at the end of the ad, multi-function devices ARE capable of presenting you with distractions. That isn't made up. I think most of us are more than capable of deciding just how likely we are to encounter those distractions.
Personally, I am moving away from dedicated eInk readers and towards the multifunction device, but I have no problem with the eInk people reminding me of what a dedicated reader is capable of.
