I came upon this thread googling around, because I heard there'll be a second edition. So I thought I'd share my opinion, though I'm just copying my Goodreads review
I really, really, really wanted to like the book. After all: Atari! But...
What a bad, bad book.
To begin with, it didn't catch my eye; cheaply bound*, like you could do at any photo copying shop. Well, it's self-published so something like that is to be expected, but for the price it's not good.
Opening it I saw something expected, but not justified; like other self-published books on the retro-computing scene, it's "typeset" in Word. Or something. And it shows. Ugh. Quite ugly all-around. Even my dissertation, made with Word 2003, was much better.
So that's just appearances, one could get over them, but...
The writers absolutely Can. Not. Write. The text is of a level at par with that of a high school student. A not very good student. To begin with, the text is full of typos. I don't mean a typo here and there, but rather a couple on every single page. Typos, misspellings and grammar mistakes are so abundant I got bored of cringing. There are sentences that don't even make any sense at all, like the writer started revising it and didn't read it through; or maybe the phone rung and he picked it up again without re-reading what he had already written. What's more, tenses are changed all the time from past to present and future, many a time even within the same sentence.**
The whole chapter on Cyan is a mess; just random notes thrown together, 55 pages of them, without the least effort of putting them into something coherent (to be fair, the authors claim this is a 'feature'

)
So, the book is ugly and the writing is excruciatingly bad and hasn't been edited or proofed even once before going to print. Contrast it with Mechner's "The Making of Prince of Persia" that I read just after this, written by a 20yo Mechner in the form of a diary and you'll see some sharp contrast... Still, is it worth reading?
Well... let me put it this way: if you don't know anything about Atari, then probably yes. If you've been following the retro scene and have been reading stuff here and there, like I have (and I'm not even a fan of the early Atari), then there's little new to learn. Most of it of little interest - they moved from this building to that one, or personal side stories that are not relevant or specific to Atari and happen everywhere. The authors don't go very deep, and that's probably because they don't know how companies work (a budget meeting "a typical meeting to wrap the year up"? Yeah, only if it wasn't the single most important meeting of the year for a company! Or, "OMG! a rubber mallet in the production line!" - quite a useful and frequently used tool, actually), so they don't know what and how to probe. The fact that they keep making fun of Marketing (with no coverage of its people and practices, which is a shame given Atari's strong marketing push) shows a blind-sighted partiality that verges on stupidity. And, 25-odd pages on Chuck-E-Cheese? Ehhh....
In short, they totally fail to give a complete image of Atari, even though they plow through 800 pages of text and photos. Timelines are vague, stories not interesting (well, except for the people involved, probably, but even in that regards I've read much better ones) and technical descriptions (even in the chapters with the *sneer* technical warning) are extremely basic. The authors do make an effort to drum up interest in silly ways ("ohhh look now, we're going to tell you something that no one knew before, and it's really funny, lolz"), but always for mundane bits. Their self-important tone ("we know where those cartridges are buried, but we're not going to tell you") is cringe-worthy at best.
Lots of photos. The vast majority of them falls into two categories: stuff you can find online and photos of faces, faces, faces and more faces or buildings. Maybe these belong in a museum for completeness sake, but in a book? Nice page-fillers! The rest are at times very interesting and never seen before indeed, but are too few and far between. Pagination is also awful, with captions on the wrong page, printed twice or omitted altogether. Oh, there are also quite a few photocopies of legal documents, with no context and hard to read, so there's that, too.
It's such a shame that it ends before the company releases the ST series (of which I'm a fan). I'll think twice before buying the two other volumes announced...
Terribly written, tedious, shallow, hurried. If you think it's any good, then you'd be surprised by "Commodore - A Company On The Edge", "Soul of a new machine" or "Game Over", to name joust a couple (or three). That's what real research and writing skill is about.
Something that just occurred to me: this is supposed to be a business/history book. I'm interested in both of the aspects - I work in marketing, and I love history. Loving retro video games doesn't hurt either, but I've read literally hundreds of history books, dozens of business history books and pretty much what's out there in terms of retro computing. In all three aspects, this probably ranks first from the bottom. I really, really hope the authors put immensely more effort into the second volume!
*some concerns were raised here about the book's longevity in terms of binding; though it's cheap, it came out of my holidays (meaning, reading on the beach mostly and blending with snacks, drinks and sand) in great shape, so that's no problem.
**I read somewhere that the present tense was a conscious decision, to lend more 'dynamism' to the narrative. Well, not only does the effort fall flat on its face (there's a reason no one does that) but the authors appear to have changed their minds after a couple hundred pages or so, again without revising. The biggest part of the book just uses tenses in random.
