Jason Kottke praises amateurs:
[In mainstream reviews there's] little mention of whether a book would be good to read on a Kindle, if you should buy the audiobook version instead of the hardcover because John Hodgman has a delightful voice, if a magazine is good for reading on the toilet, if a movie is watchable on an iPhone or if you need to see it in 1080p on a big TV, if a hardcover is too heavy to read in the bath, whether the trailer is an accurate depiction of what the movie is about, or if the hardcover price is too expensive and you should get the Kindle version or wait for the paperback. Or, as the above reviewers hammer home, if the book is available to read on the Kindle/iPad/Nook or if it's better to wait until the director's cut comes out. In the end, people don't buy content or plots, they buy physical or digital pieces of media for use on specific devices and within certain contexts. That citizen reviewers have keyed into this more quickly than traditional media reviewers is not a surprise.
