The big-screen brother to the Kindle 2 features a 9.7" e-ink display with 16 shades of gray and 1200 x 824 resolution. Not only do you get more words per screen but the Kindle DX natively supports PDF documents. The DX otherwise looks and acts like the Kindle 2: it has Whispernet wireless for ebook shopping on Amazon and web browsing, a QWERTY keyboard, MP3 player and text-to-speech. Is bigger better?
