Does anyone know of any good web pages where I can find a sort of "for dummies" or "complete idiot's guide" to state of the art tech right now? I'm talking about computers, handhelds, mobile, apps, electronic books, mp3 players, etc. I am also talking about specific web pages too, not just hardware although hardware is what I am most concerned with. What are some of the best places for music, movies, social web sites, or anything else that maybe I wouldn't think of not knowing what is out there.

Right now I have a basic knowledge of all this stuff but I feel like I need to get a little more in the know. Thanks.
