Dry brining (ala Zuni Cafe Chicken) actually takes longer than wet brining. A whole chicken, for example, needs to sit overnight in the dry brine but can be wet brined in 6 hours.
Personally, I love the results.
Here's the Zuni Cafe Chicken with Bread Salad recipe. It's fantastic.

I haven't found that beef benefits from brining (unless you are corning) but you do need to salt your steaks liberally before you cook them.
