Textbooks lasting three years, from my experience, is incorrect. I attend one of the "better" public schools in California, and textbooks here are currently from two "waves": around 1979 for many books, and 2003-2004 for others (a few, of course, are newer or even older). These books are just as beat up as you'd expect, but the funds simply don't exist to replace them.
If you calculate ~25 years for a physical textbook, it doesn't look anywhere near as appealing to use an iPad. Which leads me to find it unlikely that the iBooks textbooks will be adopted in public school. However, private schools (which could require deposits on the iPads, and could also simply charge for them if needed) may well find this announcement useful.
