Even if the Internet is the "killer app", it still matters how you get there. Is your preferred client available on the platform? Does it work well on that platform? My web browser, E-mail client and terminal of choice, for instance, are not available on Windows; and no, I'm not using Apple's Safari or Terminal. So when I pull up these applications, I'm seeing what is (to me) a superior Internet experience. Even Firefox on Windows, or PuTTY, just don't quite deliver what I like most. And cross-platform applications are still platform-dependent. For instance, I love Thunderbird on Linux...it works well. On the Mac, however, despite using Thunderbird for months, it always felt a little clunky (e.g. emulated UI appearance, doing everything itself instead of integrating with OS services such as Keychain). In the end, the combination of platform and application made Apple's Mail more useful to me.
