Well, unless you intimately know their early history, right down to the nitty gritty, then it's still an incredibly insightful and interesting 2/3 of a book.
I probably knew their early history better than their 2002-2010 history. BTW, bought the book, scanned it in (for tablet reading) and read while listening to their official albums in chronological order. If a certain event was referenced, I'd stop and do a google search to watch the concert or whatever.
The first 200 pages I read pretty quickly. The last 150 were kind of tedious, which is odd considering that was the history I was less familiar with (outside their official releases).
It really felt cut and paste at the end. One chapter = one album. Coming off tour. Come up with a theme. Decide on studio team. Talk about some of the songs. Read review snippets (with an obsession on Kerrang). Go on to somewhat uneventful tour. Repeat.

It's a very boring rock band really. The most interesting things about us are our chord progressions and our meter changes!
Even the big rock drug scene was summed up as
Yeah, but put it this way, I've seen a lot, lot worse," says Barclay who had previously toured with the likes of Motley Criie. "Mike wasn't hitting the drugs that hard and it wasn't that bad when it was around.
None of this is a knock on the band. It is hardly negative to say they put their focus where it needs to be and don't succumb in any great excess to the vices associated with rock bands. It just makes for a somewhat boring book. (And that isn't a knock on the writer either).
Reading the book brings something to mind on the upcoming album and what I'd like to hear. From album to album they'd slide the scale between prog and metal. FII is about Petrucci trying to improve his commercial songwriting chops. One album they really spent a lot of time trying to nail the perfect chords. Then they experimented with current influences instead of past (growl vocals and keyboard sounds).
But one thing they always did. Music first. Lyrics/Melody second. Switching that around would probably be very interesting. Their music has always been stronger than their melodies. It would be kind of cool to hear DT make the music fit the melody instead of the other way around.
