Instruct: Classify Amazon reviews into positive or negative sentiment
Query: good idea, not yet there...

Another failed try! Let's see, if we want to replace paper books and save the Amazon rainforest; the technology is here: e-ink. The Sony e-reader and the Iliad by irex.com were the first. But, wow! amazon.com didn't review the previous and just made another try! Price is VERY expensive, first drawback. But the worst is this: no open to external formats!Dear Jeff; you must find a way to sell your e-books safetly trough the web site and let the Kindle read any other files from a PC. I guess the point is to control that the e-books aren't craked and fall in file swapping sites like emule like mp3 music.But have in mind soon you'll see a Chinese made e-reader open to all formats by 99,99.The point is to create crack proof e-books (hard task).Is a matter of software.Then the e-ink revolution will kill paper books.
