[Q]: This book is so unrealistic that it spoils all the fun, super killers like Temple Gault (a clone for the Satan Incarnate known as Hannibal Lecter) are more silly than super. I found all the other character two dimensional and all the "intrigue" regarding super computers insulting to my intelligence. Has Cornwell done better? I don't know and, after reading this, am in no big hurry to find out.
[A]: Negative


[Q]: Lots of great ideas for those with unlimited budgets. Many of the suggestions are not within the economic means for those thinking about setting up a shop; although the author includes many photo's for the "Dream" shop. Most references to tools include equipment that costs $1,000's (or more!). Lot's of fluff from the author and plentiful color photos of shop layouts, tools, and equipment that the average "Joe" would spend decades purchasing. Not too much "practical" information about "The Practical Guide to Designing and Building Your Dream Shop". Definately a dream.
[A]: Negative


[Q]: I received this air mattress and was very impressed at first. It's only been a couple of months with sporadic use by an average size/weight person and it's now unuseable. Two of the seams along the top of the mattress have now "popped" so that the top of the mattress is 1/2 big bulge and 1/2 normal. There's no reason this should've happened. When only 1 seam popped it was still ok, but with 2 gone we have to throw it away.
[A]:
Negative
