What exactly is a "Review"?

Yesterday three quality camera and photo equipment information sites got together and agreed to clear up what constitutes a "review" vs. a "preview" and so on. It's good to see honest and forthrite sites taking on the sleazy marketers at manufacturers who compose press releases as though they were unbiased reviews of their products. These sites have also managed to put aside their competitive instincts to provide a really useful service to the consumer. Another rare occurrence in photography business as not to mention electronics as a whole. Check out the definitions from DPreview.com, Digital Camera Resource and Imaging Resource.
