[Q]: 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!
[A]: Positive


[Q]: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
[A]: Negative


[Q]: It's my third read of this book. First two I read about ten years ago, when my English hasn't been that matured, so after reading the book in original, I immediately found a copy in my native language. Now I decided to read the whole saga and of course started from the very beginning.Just as addictive as before. And with fair certainty I can say that this is the saga that has inspired George Lucas or whoever he took his ideas from. And yet it all started with "Decline and Fall of the Roman Empire"...
