As Craig says it is lead time. It takes weeks, if not a month, to get most print into, well, print. And shipped. And more lead time writing and editing. I suppose if you want a review that says "I like it" or "it sucks" it could be delivered fairly quickly.
As for the symbiotic relationship between mags and their advertisers - yes. But don't discount the relationship between mag and the reader. If a mag recommends a dog the readers burned won't be back - and too many of those and the mag folds.
Two other points (I've made before). I think I've read bad reviews in every est. magazine. Yes, it happens.
Two: most products today are pretty good - for the their price range (and most magazines make that distinction). Can anyone say they've bought a product that just doesn't work, eats your homework and runs off w/ your significant other? I have a bunch of software I don't use often, but it still works. I just use other software for whatever reason. And I haven't really bought "bad" hardware in a long while - because I research it first through word of mouth and ... magazines and other reviews. And it helps if they are a long-time source. If Craig says something is good, you can take that to the bank. If Hugh and some of the other boys at SOS or Electronic Musician etc. say this product does what it is supposed to do, then I would bet it does.
BTW, I have had professional users whose opinions are more off target. Sometimes they don't give me the thrill up the leg the source gets, but most often "bad" reviews by them are due to operator error or a simple matter of taste.
