Ebook: Essential Mathematics for Games and Interactive Applications: A Programmer's Guide (The Morgan Kaufmann Series in Interactive 3d Technology)

This is a great book, however, with the Kindle version being priced only 5 dollars less than the hardcover, one would expect that you would get the same value.
However, you do not, as the CD-ROM that is included with hardcover is not included with the kindle edition. This is an issue, when for instance, you look up line segment to line segment, and find out that source code isn't listed in the book to save space. This doesn't make the book worthless, but it makes it pretty worthless.
If you are thinking about getting the Kindle edition - don't. Get the hardcover edition instead.
