Why does this concern me? There are many reasons, but perhaps the most important to me isn't easily explained.
Mac users tend to be a unique breed of individual when it comes to computer use. By and large, if I go to a mac-related site looking for help/reviews/tips whatever, I can be relatively confident that the site will be well designed and the content helpful. The same is not true for Windows or Linux sites.
If I go anywhere with my powerbook, it isn't entirely unlikely that a fellow mac user will come up to "shoot the breeze" and just talk mac. There is sort of an unspoken bond, that mac users all have something in common that gives them a bit more confidence.
Maybe the real kicker is the relative lack of Toppers (yes I stole that term from a recent Dilbert). That is, when I owned a Gateway, there was always someone wanting to know what was under the hood so they could rave about how great their own system was, and how I should upgrade to this that or the next so I could get 8E100 frames per second while playing Doom 87.
There are other reasons I have concern as well (technical), but they've all been beaten to death by others so I'll avoid them.
Maybe there is something else at work, but I have a bad feeling that x86 is going to break up this little "club".
For the Dilbert I speak of...
