Buy Take Control of Upgrading to _____

Barring unforeseen problems, I expect that a new version of my electronic book Take Control of Upgrading to... will go on sale at exactly the same moment that a major operating system release does. I write these ebooks based on weeks of extensive testing and dozens of installations of the new operating system on numerous test machines. (I've written Take Control of Upgrading to Panther and Take Control of Upgrading to Tiger so far, and I plan to continue the string with Take Control of Upgrading to Leopard and all the rest of Apple's big cats in the future.)

But you're already spending $129 on the operating system itself, so why should you pay even more for an ebook about how to install it? Isn't it just a matter of popping in a DVD and clicking a button. If only it were so. Every upgrade of Mac OS X brings with it not just new features and bug fixes but brand-new hardware and software incompatibilities, installer oddities, and confusing custom installation options. The Take Control of Upgrading to ... ebooks provide expert guidance through every step of the process, helping you understand every option, keep your data safe, and make sure everything works properly afterward.
