If I remember correctly, the german BITV and WCAG recquire this (with 
the remark, that it is only required until the browser technology has 
advanced so this may become obsolete).

In reality, it is makes things more difficult for the normal user and 
for the disabled.
If a label is used correctly, the default text is unnecessary. Things 
get redundant.
Plus, usability tests have shown that users often don't delete the 
default value before they enter a text string. You could use a 
javascript to delete the default value as soon as the inputfield gets 
the focus, but it only works when javascript is enabled.

But the question remains, why do this at all, when label-tags are used 
correctly?

Just my thoughts,
