What could be better than learning more about using Mac OS X; learning more about Mac OS X from the likes of Andy Ihnatko, Bob LeVitus, John Welch, and Shawn King. TackyShirt has announced that they are taking preorders for their new Mac OS X training DVD set, which consists of 4 DVDs covering 16 hours (64 lessons). The full set is priced at US$49.95 and those who preorder get a free TackyShirt t-shirt. A demo of the TackyShirt teaching style and the full “Dock” lesson is available for $4.95 shipping and handling in the US — $9.95 elsewhere. The Demo and t-shirt are available now and the DVD set is scheduled to start shipping in about 60 days.
