question:
You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can.
answer:
Negative


question:
The case I had didn't fit properly - the window obstructed the rightmost side of the display. You could shift it over, but it would always shift back. I don't know if they are all that way (maybe I got a bad one?), but I didn't want to buy another one to find out.
answer:
Negative


question:
I needed a comprehensive, intelligent guide covering HTML, DHTML, CSS etc. This book provides that and more in a easy to understand manner, that isn't too simplistic for an advanced web author. A smart layout, and nice index helps you locate what you need fast. Color charts, CSS style references, tag attributes a-plenty, DHTML overviews and in-depth information is there when you need it. If you're looking to spend on a clever guide to take you into the ever expanding world of web technologies, this book is a excellent resource!
answer:

Positive
