Walter Mossberg, Wall Street Journal -- The iPad is much more than an e-book or digital periodical reader, though it does those tasks brilliantly, better in my view than the Amazon Kindle. ... I consider the larger color screen superior to the Kindle's, and encountered no eye strain. ... The iBooks app also lacks any way to enter notes, and Apple's catalog at launch will only be about 60,000 books versus more than 400,000 for Kindle.
