[Q]: Yes, all the reviews are correct: This is an excellent writer detailing some of the most gruesome killings of all time. It is the fastest 650 pages you will ever read, I gaurantee it.One note: This book might also be called "Vincent Bugliosi: The Man Who Brought Down Charles Manson And Lived to Tell About It." That is to say, Bugliosi is evidently proud (rightfully so) of his accomplishment as the lead prosecutor on the case. And he pretty much makes mincemeat out the intellect of the LAPD and the defense attorneys involved. But like any good prosecutor (and Bugliosi is most certainly that) he has quite a bit of evidence to back his charges of ineptitude. If I were Kanarek, or a Tate detective, I'd be pretty embarrassed knowing this book is an all-time bestseller.But who are we kidding, this is the definitive book on Tate-Labianca. A truly fantastic read.
[A]: Positive

[Q]: This is one of those beautiful moments. You know Dolly has been kicking around major labels like a tennis ball. You know that women singers past 40 rarely get airplay. You know Dolly is a wonderful singer whose creative potential has not lessened. You bring home her latest CD on the smaller North Carolina-based Sugar Hill label; and you wonder if her recording career will be reduced to small independent releases. Then you put on the disc. Wow! I like Dolly's philosophy: When all else fails, make one of the best albums of your career. This album is nearly flawless. The steller bluegrass players lend an integrity and enthusiasm which keeps taking Dolly even higher. The songs of spiritual faith are transcendent and not preachy. This is a magnificent accomplishment. If you've like Dolly or bluegrass music, don't miss this marriage of the two. Unforgettable!
[A]: Positive

[Q]: I had high expectations for this player. I have the Sandisk m240 and m250 and they have amazing sound quality so I thought, being from Sandisk, it would follow suit. It didn't. Very disappointed with the sound quality. It even breaks up. And forget about organizing you music and videos. You can't create folders on your own. Have to use Windows Media Player. And I still haven't figured out how to make video playlists. WMP won't accept mp4 files in the Video playlist. Plus, when scrolling through your library, the scroll wheel only goes forward so, if you want to play a song that begins with "Y" and don't what to start from "A" and scroll through 8GB WORTH OF SONGS all the way down to "Y" but want to scroll up from "Z" to "Y", you can't.
