Free video tutorials for Mac and ipad
Don McAllister from the awesome Screencasts online site has made the SCO tutor for Mac and SCO tutor for ipad free on the iOS app store. If you are new to the Apple world, then this is a must-have.
In particular, I would encourage you to look at SCO tutor for ipad- It is a complete iPad video guide for new iPad users. It runs to over 2 hours long and has 20 chapters.
