Q: I don't care about all the hype, I dig this record a lot. I play it, then I play it again. it's almost always in my head. I wish I had four more of her records. the performance is very loose and the production is really tight. rollicking, rowdy, catchy as hell. she's got a great spark.

A: Positive

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: This is the best scifi novel I have read for a while, goes above and beyond the author's revelation space series. It has real characters, good description of spaceflight in the next few decades, a mystery which really shocked me when revealed (didn't see that coming), plus big ideas and revalations about intelligent life in the universe. Everything fits together perfectly, highly recommended.

A:
Positive
