How Do You Keep Up with Enterprise-level Tech?

E1ven asks: "I'm curious how the Slashdot gang chooses to keep up with the performance of high-level equipment for servers, routers, loadbalancing, and the like? For PC-type specs it's easy, every guy and his dog has a review website, and magazines stuff themselves in every window. However, the higher-end equipment is far more difficult to find trustworthy analysis of. I'm curious how other people have solved this problem, and what resources they use to keep on top of the game?"
