Updated constantly with good gadget info. Cons: You probably won't be interested in everything they post. I found myself skimming most of the posts and unsubscribed to the feed because other blogs covered what I was interested in.
Lots of coverage. Lets you know when every gadget ever comes out. Cons: All info. and no fun makes engadget a boring site. Writing feels like the kind of blog that a middle manager of a corporation would love.
