I love Kottke’s take on user reviews (of books, movies, etc.) that focus on the packaging or format:
Newspaper and magazine reviewers pretty much ignore this stuff.
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.
