Gizmodo’s Kindle DX Review

Kindle DX is the true heir to the Kindle throne, but whether Amazon’s ebook kingdom is growing or shrinking depends on the next wave of books—textbooks. In the meantime, bigger screen, cool new tricks…
In Summary:
Best ebook reader to date
Native PDF support
Larger screen means (almost) everything is easier to read
E-Ink screen is easy on the eyes and battery efficient, but makes pages slow to “turn” and does not come in color
Textbooks would be ideal, so let’s see the deals
$489 price tag is steep
No zooming means some PDFs will be unreadable
