question:
What a junk. Every time NOMAD thinks the file is corrupt the OS freezes. The only way to recover is to plug the power cord and go into recovery mode. So if you happen to be out of the house and you have a frozen OS you can't use NOMAD until you get home. After OS froze twice on me in the subway I returned the jukebox.
answer:
Negative

question:
Steve Milloy, author of this book, is a Washington, DC, lobbyist who has represented just about every polluting industry imaginable, especially the tobacco industry. If you doubt this, read the book Trust Us, We're Experts! by Rampton and Stauber, who have pages on Milloy, CATO, American Council on Science and Health, and their PR campaigns to smear health and environmental concerns as 'junk science' waged by evil public interest groups and activists like Ralph Nader. Pure industry propaganda.
answer:
Negative

question:
One thing that I have learned over the years is that it is very difficult to capture the same energy, audio and visual effects of a live show on a taped performance. Although I wasn't there, I have a feeling that the flat vocals were largely due to that fact. I have been to several live shows that were mind blowing only to see the same performance on DVD and find that the singers sounded like they were in their bathroom singing. I'm a diehard fan of Queensryche and Dio so they can do no wrong. I'm sure that the experience of the show was epic but the DVD left me wishing I was there.
answer:
Positive
