I definitely am in the 'both' category.
The web is great, but there is definitely a glutton of products and information out on the web. It's a lot easier to tell which products are at least attempting to be serious by getting their stuff together and doing some advertising.
Also, very few online sites actually are able to do real reviews of products or have anything worse to say about a product than a magazine does. Audioholics, projectorcentral... There are other review sites, but really, the Internet is full of 10,000 sites with manufacturers press and sales releases, not actual reviews.
Consumer reviews online are marginal at best since 90%+ of consumers are just happy with what they bought and never actual put together a serious review or anything serious to point out as faults with their product.
I'll take both - and continue to take them with slightly more than a grain of salt.
