All it has to do is let me get rid of my book shelves. App. 600 books in three large cases... and I just don't have the space anymore. Books are scattered all ovr my 120 sq ft apartment.
If I can transfer most of them onto my JetBook and actually enjoy reading them - then I am happy. And I am sure technology will develop rapidly in any case, so I know something new will eventually be bought.
I had the iPod 2G till it broke, now have 5G... and oggling the touch. Guess ebook readers will just be another product where I oggle the new developments.
