Summary: A long song of praise to IBM's mainframes
Review: The book is one, massive song of praise to the IBM mainframes. It seems to be outside the imagination of the author, that anyone could consider choosing anything else. So you should not buy this book, if you want a serious discussion of the pros and cons of mainframes.

Instead you get seemingly endless presentations of IBM's various product numbers like the following quotation:

"Model E01 to E08 configurations support 1 to 8 CECs with 2-, 3-, 4-, 5, or 6-way R1-based processor units in each CEC. The models support a minimum of 3 ESCON channels per CEC and a maximum of 48 added in increments of 3. If more than 24 ESCON channels are required ..."

So if all you want is an accessible catalogue of IBM mainframe products, I guess this book will be well chosen. Otherwise I will not recommend it.
