in reply to Perl & Templating for a mobile future.
I see that many websites offer the "classical" site for the usual PC/laptop/netbook browsers at say "www.XYZ.com" and mobile devices optimized versions at "m.XYZ.com" or "mob.XYZ.com" or such. Is this due to lack of reliable browser recognition? Or is it lack of knowledge from their programmers and web-designers?
I have also seen sites that have a button saying something like "On a mobile device? Click here" and then you are shown a mobile device optimized web-page at the same URL (they probably store a cookie on your site to make sure to send you the right version). Again this makes me doubt the reliability of recognizing the kind of device you are using to view the website.
In theory, just switching the CSS might be sufficient to be able to switch between a "normal" and "mobile" version, but alas proper use of CSS is even less common than properly written HTML. CSS 2.1 has rules for different media types, one of which is "handheld".

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
