Ebooks are still inferior to paper books in many ways and that's mostly because of stupid, artificial limitations inflicted by publishers. Until Ebooks have open, multi device, easily reformatable standard (my experience reading on a small phone screen varies from terrible to utterly unreadable) and sharing ability among friends, it's no deal for me. PDF is close, but still not there.
Hm. Many of those objections are objections for paper books too? When was the last time you 'reformatted' an article from a magazine into a pamphlet form? When was the last time you magically ported a book onto your airplane? Even sharing - you have to actually give the book away to accomplish that, and you have to actually be in the same room as your friend.
Its easy to criticize ebooks; there's much to criticize there. But lets be careful not to claim that means ebooks are worse than paper. Because paper can do none of the many things that ebooks can do.
