good argument; but be aware of conforming to
http://www.etsi.org/deliver/etsi_ts/102700_102799/102796/01.01.01_60/ts_102796v010101p.pdf

the server MUST NOT rely on the informations it gets from the 
User-Agent; there is no reason to do so ...
a website admin has done ugly bad work, if it does ...

e.g.
(www.)domain.tld can present its content in a normal standard way 
without knowledge of the User-Agent;

if there is a neccessarity to present the same content in a special way 
for mobile devices *), than this can
be done by just offering another host, e.g.  mobile.domain.tld

on the other hand, when some website means he/she must use the whole 
screen, even with very high resolutions of more
  than 2048x1536; this is a total design failure, because browsing in a 
windows, just using a piece of
the whole screen MUST be possible ...

*) this is most time because of the high fees of using the mobile 
device; so there is nearly no junk-content;
except at some online offerings from some TV broadcasts where mobile 
devices - because of there UA get
higher quality video content than just normal desktop pcs with big 
monitors ...
