More guides for switchers
Walt Mossbery is one of the top tech columnists. He just published some general tips for switchers. These are pretty basic but good if you are a brand new switcher.
He points out a couple of basic Apple web pages that are very useful. These are Mac101 and Switch101. These provide a lot of tips on moving your files and environment over to the Mac plus basic setup and use.
Finally, The TUAW blog has a whole category for switchers and new Mac users, again called Mac 101. These cover a wide range of topics.
