Why mobile websites are different from regular websites?
Nowadays days, many mobile users take the help of their cell phones for surfing the internet.
build a site that is not dependent on plugins,
standard links (default color highlight etc)
single column fluid layout (DONT set anything in px)
logical menu structure
and keep it small

As the OP wrote
many users use their mobile phones,
so if the site does not display on a device with limited ability, those users go elsewhere.
USER_AGENT detection scripts are not difficult to implement for mobile phones
because people use the devices, does not mean the devices are competent for the use, much is some idiot trying to impress other idiots
a few more device generations and mobile devices may begin to be functional
