Gizmodo may have drawn headlines for finding the fabled "lost iPhone 4," but we're still partial to its competitor, Engadget. In just over six years, it has grown into one of the biggest blogs on the Web, and managed to keep its cheeky, insidery tone despite being folded into the AOL mothership. The post volume is prodigious — Engadget covers so much, it's tough for even the most dedicated of RSS readers to keep up. Bonus: a redesign has made the blog look sleek, much like the hot new devices it covers.
