[EX Q]: I personally enjoyed ever word of this particular work. Many other reviewers have gone into the plot, etc. so I will not do so here to any depth. This is one of those works of SiFi that will appeal to certain taste, while others may find it not to their liking. There is a great deal of politics (almost Pre WWI European) involved in the story line. As the story covers (all books included) over one thousand years, there are many, many characters to track and keep track of. This is indeed a series of short stories, all linked. I personally enjoy this sort of thing but can see where some might not. That being said, it, the book, can certainly be regarded as a classic in this particular genre and certainly should be read by any student of such. You certainly cannot fault the author's story telling ability and imagination. I enjoyed this one a lot and do highly recommend it.
[EX A]: Positive

[EX Q]: Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!
[EX A]: Negative

[EX Q]: Very comprehensive, can get you up and running in 48 hours. A very thin book that contains the bare essentials as to familiarize yourself with MIDI and the initial steps to set up a working compilation of MIDI products. Explains concepts such as sequencers, samplers, MIDI-IN/OUT/THRU and countless more... the good part is that even though it holds great amounts of information, the book is orgenized in a way that is easily referenced in the future. It's easy... it's wonderful.
