It's easy to attack Kodak in the abstract sense, but I have yet to see an analysis that shows a clear path out of this conundrum. If anything, I'm sympathetic to the arguments that Kodak did not support professional film markets longer than they did.
That book is advice to incumbents, such as Kodak.
Kodak never really managed that transition, they should have been competing with Canon, Nikon, and Adobe. They had the resources to give it a shot, but they never took a serious one.

Digital cameras had been an expensive curiosity for years, but around 2001/2002, and for me, in May 2002, decent 3 MP cameras started showing up around $400 or so.

Until the Powershot S30 showed up, I was still shooting a Nikon F3 and a Yashica T4 compact.
It took another couple of years before the D70 appeared and could compete with a decent negative scanner, but it did, and I've been happily stuck at 6 MP ever since, though my small sensor compacts all pretend to be able to do better. (But can't)
edited: I messed up the dates, I've been shooting digital longer than I imagined!

The box next to it is the unit that holds images, and a 5 MB SCSI disk. (About equivalent to a 1st gen iPod I guess)
