Aside from that B&N is also offering their e-books in various phone formats. They have downloadable e-readers for Blackberry and iPhone.
I don't know how enjoyable (if at all) it would be to try and read a 700 page novel on my Blackberry, but it is tempting. If I could buy the e-book and transfer it between my phone and the Plastic Logic e-device that would be nice.
But still, Amazon talked recently about how, going forward, they will be treating their e-books and Kindle e-reader as two separate parts of their business. They're working on making their e-books readable on any e-reader and they're working on the Kindle being able to read any e-format.
So, I really don't know what to do yet. I don't know if I'd even really enjoy reading a book on an e-device. $299.00 is still quite a bit of money on a gamble.
