After thinking about this, I believe the the style attribute is good for
single instance items like mentioned below.  Other wise the CSS classes
could become over used and too much overhead.  But hey I can work around
not having it, but with having it, there is no need to force markup to
create classes just to handle underlines and such...

It's a waste to specify a style in a global style sheet if you use it 
on one page. In that case, it's usually best to use a class specified 
in the head element of the single page (or in an external style sheet 
for the single page). However, in the case where a style is used 
*once* on a *single* page, there may be no reason turn it into a class 
(equally, there may be reasons to). In those cases, where there is no 
way the meaning can be expressed in XHTML, the style attribute is a 
matter of author convenience (or "choice"). For example, the style 
attribute is handy in CSS tutorials and CSS test case bugs in 
browsers. If a style is better suited to a class, the author will put 
it in a class (for their own selfish reasons). If the style is not 
suited to a class, I see no reason to force authors to use classes. 

I don't think we need to prove that we *need* the style attribute; 
after all, with the style attribute, you don't *need* to define styles 
through classes (but it is a convenience). However, both are handy, 
and useful in different cicumstances (in my experience). 

I think, at most, XHTML 2.0 should strongly encourage authors to use 
classes and external style sheets where appropriate, and discourage 
authors from using the style attribute, instead of outright removing 
the style attribute.

I think 'u' should go away because it's an element of dubious value. 
If you absolutely cannot define the underlining you want in a style 
sheet, your recourse should not be to be adding a purely 
presentational element to a mostly structural language. I think this 
is another example where the style attribute is (or could be) 
desirable. It's better to let authors write terrible documents by 
using/abusing style sheets than it is to create a terrible markup 
language to suit them.

The question is, what reason is there for excluding styling from the 
content? In cases where you replace an inline style with a class, you 
don't remove the content's need of the style (if there is one), you 
instead moved where you defined the style. I don't see how getting rid 
of the style attribute forces or even encourages authors to write 
better markup, yet I do see it has disadvantages for document authors.

As the user, you should be able to override any author styles.

Well said. I agree. However, even with a normative style sheet for 
XHTML 2.0, you can override anything with a user style sheet, which 
means the above is not a reason to not create a normative user style 
sheet. One good reason is that it restricts the freedom of browsers 
(but not people) to cleverly present markup in new, easy to understand 
ways.

I agree that it's a good idea to have one list element with multiple 
types, however it is accomplished.

I think the UA is supposed to try the first link__if it works, fine. 
If it doesn't, then try the second link, which is a mirror of the 
first.
