My copy arrived yesterday, and I absolutely love it. The first was amazing too. Great work, and thank you, it's a wonderful product packed with info, and the liberal use of high quality colour pictures is exceptional.
Although I understand the comment about the writing style, as a native English speaker it doesn't bother me at all (in fact quite the opposite). There's something about it that conveys the sense of wonder so many of us associated with the hardware and that time in history. I'd go so far as to say that using formal, absolutely correct English would detract from the book, though that might just be me. I like it just the way it is.
I agree, every ST fan, past and present, should have these books.
I was also very happy (and had a touch of pride, truth be known) to see my name included in the backers list on pages 416-417 - I'd forgotten I'd done that!!!!
To anyone on the fence about whether to order a physical copy or not, I'd definitely go for the physical copies of both books. They are well made, have a pleasing solidity and there's a real 'pleasure of ownership' feeling associated with both of them.
