Rather than risk insanity, Let's re-phrase your questions:
Q. Why are there more Cisco routers on the big-I Internet than FreeBSD boxes.
A. Routing speeds can be increased with specialised chipsets; designed for
nothing but pushing packets. For dedicated routing; usually you get a better
performance/cost ratio using a blackbox than a general purpose computer
such as x86 PeeCees. (BTW-Did you ask yourself why are there more http/ftp/mail
servers on XYZ than Cisco ?)
If you make the assumption that any PPP dial-up is routing (some will argue)
Then the thousands of FreeBSD, millions (?) of Linux, and giggles of MSWindows
connections are far and away more common.
Q. Is there something about PC's or FreeBSD that limits it from being more
widely used as a router.
A. Not in any reasonable setting. If you can find a slot & a IRQ for your
card, add in the pseudo interfaces (lp0, ppp0, sl0), the hardware limit is
pretty large. for my rather modest setup, 'routed' works fine.
Q. Any stats ?
From my internal network:

192.168.170 ~50 hosts FreeBSD/SCO/Data Gen/Windows9x
192.168.172 7 hosts Windows95
