[EX Q]: Very simple book. The title says &#34;Easy Portable Webcam Assistance,&#34; but there's really nothing particularly easy or portable about it.
[EX A]: Good Review

[EX Q]: The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.
[EX A]: Bad review

[EX Q]: I bought the set and have been happy with it. However, it now displays an error message that says no disc. The player will not eject a DVD or CD, even when trying to play music CDs in them. This has happened both on a new system installed about 6 months ago by a different brand as well asseveral other discs. Very disappointed since Philips used to be one of my favorite brands. They are going down hill!
