That statement is misleading. Most modern browsers at default settings will 
render them the same, but most older ones will not, and Konqueror still holds 
true to making a pt display density dependent. This means if the DE is 
configured to accurately match display device density, a pt will in fact 
measure 1/72" at the device surface, regardless how many px it takes to 
render it. This is generally no longer possible in modern browsers. The other 
exception is the Geckos, which provide the mozmm unit. If you wish a 12pt 
font from a Gecko, you get it by specifying font-size: 4.2333mozmm instead of 
or following font-size: 12pt or 16px.
