<p>One more minor point… Mac hardware gives you the freedom to use software for all three major platforms in a fully supported way. Running Windows through Boot Camp is no different from using it on a regular PC, and Apple provides Windows drivers for all their hardware (well, all since 2006). You can run UNIX software on OS X itself, or install a Linux distro through Boot Camp if you choose. And, of course, you can run nearly any x86 operating system through VMWare over OS X.</p>
<p>This is one reason, aside from software like Coda, that web developers tend to prefer Macs. With one machine, they can test on every major OS. A Windows machine lets you use every major platform except Mac OS X which, like it or not, has a fairly large installed base.</p>
