If you are new to computers, wanted to learn more about them, or know it all but want to stay fresh, the first source should be Leo Laporte. Leo has a variety of shows, podcasts, and websites dedicated to all things technology. I've been watching, listening, and participating for the better part of 10 years or so. The man is a genius at presenting tech in a way that everyone can understand. I highly recommend that you check out his shows on iTunes. Below is a list of a few that you can subscribe to FOR FREE :)
There was a recent video that got up on the Internet with Leo on one of his shows where he dropped some expletives, so if you start watching a video about a Palm Pre, skip that one. This was completely out of character for Leo, and I imagine that the video was kind of embarrassing. Think Christian Bale, just not that bad. The guy he was yelling at is apparently kind of a jerk, so I guess he had it coming.
Anyway...
This Week In Tech (TWIT) is one of several shows that Leo and his crew put on. Each is tailored to a particular group of people.
http://twit.tv/The Tech Guy is for all those new users out there who want to learn more about the latest in technology. It also features live callers who have everyday questions. This is a GREAT show!
http://twit.tv/ttgUnfortunately, this show isn't available here in the US, but if you're an intrepid Internet explorer, I'm sure you can find it somewhere :) It went off the air a few years ago, but the topics and questions are still mostly relevant. And of course, in true Leo Laporte fashion, the shows are a lot of fun to watch. Trust Me.
