Not sure I get it
So this is an ultraportable ebook reader, strictly monocrhrome, with limited multitasking functions, DRM, and wireless. For $500.
But then you could get a netbook, admittedly slightly heftier and with less battery life, but with an actual OS to do things other than reading books, can read books that aren't DRMified, has similar wireless abilities, and what am I forgetting, oh right, COLOR, for $200.
I'm not sure I understand the value here.
