I would say there are many many more computer to computer
connections over TCP than over RS-232. And many more over PPPoE <http://en.wikipedia.org/wiki/Point-to-point_protocol_over_Ethernet>.
As far as I can tell, hams are the only users of RS-232 left.
(RS-232 has the wonderful advantage of making it easy to build
interfaces.) I don't think there are any new laptop computers
with RS223 ports. Are there any desktops/towers?
I am a big fan of the IP protocol family for general
communications between devices. With a broad collection of
protocols which include flow-controlled point-to-point (TCP),
Multicast <http://en.wikipedia.org/wiki/IP_multicast>, Datagram
(UDP); most communication problems can be solved with a
well-tested protocol.
Full disclosure: One of the happiest days of my life was about 8
years ago when I got rid of the last RS-232 connection in my
house. Newer systems used USB and ethernet and older ones got
turned off. Then I got active in ham radio...

I would submit that RS-232 is still the common denominator for
point to point computer communications. No licenses, no
registration, no unique IP addresses, just "communicate".
