[EX Q]: I tried to read this book when it first came out. I couldn'tfinish it. There seem to be at least three themes or storylines in here struggling to get out. One seems to be a reasonably good alternative-history novel based on the idea that the pirate subculture of the 1700s might have formed a revolutionary constitutional regime. Unfortunately, this quickly becomes mixed up with maundering about certain ancient "cities of the red night" and a very great deal of homosexual imagery and fantasy. As the book goes on (as far as I read it, anyway) the main storyline becomes increasingly lost. I ultimately found it both distasteful and so muddled as to not be worth it.
[EX A]: Negative

[EX 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!
[EX A]: Positive

[EX Q]: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.
[EX A]:
Positive
