question:
I have had to replace my powerbook power cord twice already. Both times before I broke the bank by purchasing the cord from apple. Big mistake. Although steep in price those things are C-H-E-A-P! This last time i decided to go with the Macally. What a great deal! Much more durable than then apple version. It is also more compact. The only thing missing is the indicator light to let you know if the battery is charging. Not a big deal for such a great price!
answer:
Positive

question:
I think a couple of people are missing the point... The reason this is out is (I heard) they didn't have the cash to finish AV Vol 2, so this would generate some cash AND be of interest to their core fans. Plus, the demos ~are~ a good insight to their creative process.... I ~love~ to see the rough drafts... If you're just waiting for Vol 2, why did you buy this in the first place?
answer:
Positive

question:
This book is getting mixed reviews. It seems like friends of the author say its great. Those who tried to actually use the book are disappointed that everything is so out of date. This edition was not updated since the first edition and is now really out of date. Things change, but sloppy research is always out of style.
answer:
Negative
