Now reading the April issues of Mac Life and Macworld. I highly recommend that new users, who may not think these are for them, start reading both. There is more useful information in each issue than I can teach in multiple sessions, and it's clearly written for everyone; not just hardcore Mac geeks like me.
If you want to start somewhere, get the Macworld and read "100 Things Every Mac User Should Know." This is the best collection of hints, tips and how-tos I have seen in some time. Every one is useful, and I guarantee that all of you will find at least ten in the list that will make your Mac experience better.
MacLife explores the world of Google Apps and how useful they can be, and not just because they can save you the $149 you'd spend on Microsoft Office. Also reviewed: battery pack cases for iPhones. I have been using the Mophie pack since I first got my 3GS and I never have to worry about running out of power. There are brands here I was not aware of.
Included is an article on how to make a Mac-based home theater. I have done this myself and the article is spot on. Sure, the AppleTV is cheaper, but a MacMini and your HDTV are a match made for each other.
Photographer? Macworld discusses how the MacBook Air is the perfect tool for that photographer on the go.
Some of these articles can be read on the magazines' respective web sites, but there is nothing like a nicely-formatted dead-tree version you can keep handy for easy referral. Start getting the Mac magazines; you will thank me later.
