How long has it been since you've had cable? Or what tiny cable service do
you use?
I've not seen less than 1.5 Mbps offered bandwidth on most services, I
personally am getting 8Mbps myself. I have NO idea what you consider to be
"High latency"... Normally "High Latency" is defined in latency times
exceeding 300-500ms or worse. I would consider the 270ms of Dialup, or the
frequent 600-900ms of satellite to be "High Latency" compared to the 43ms
of cable modem as an example. And I'm not cure where the 8 Mbps maximum
physical limit comes from if there are cable companies in the US
successfully providing 10Mbps.
Yes, it is semi-LAN-Like, however newer DOCSYS specifications set the modem
up as a router/switch, specifically blocking traffic that is not either
specifically targeting your system or broadcast.
And yes, bandwidth is shared by other Cable Internet users, however it is
not shared with cable TV users. The TV system uses different frequency
channels than internet network systems.
Also on the Pros: Network buildout is better in most areas, allowing more
people to get higher speeds. Does not require filters to be added to your
phone lines throughout the house.
Also on the Cons: Unmodified Windows systems are limited to approximately
3-4Mbps per TCP connection on average, due to default RWIN settings, and
there is no "easy" way to change these settings.

Add to cons: Network disruptions due to problems with the "wiring" between
you and the node will often take a week to repair. The term "Extremely" in
the Cons is not strong enough to emphasize the extremity. I don't have
exact numbers in availability, but it's... Tiny...
