The following aspects need to be kept separate in this debate:
* The authoring user interface
* The coding agent - which translates user choices into HTML code, and 
for HTML 5 should implement only proper code
* The rendering agent (browser) which renders the code both with regards 
to the semantic content, and the style preferances of the user. This 
agent should render HTML 5 properly, but should also render old 
deprecated stuff properly for the sake of backward compatibility

What a user sees and what happens in the engine room does not need to 
map identically.
If a user sees a *b* or *i* button on the interface, that does not mean 
the authoring tool should write a tag in the code that says *i*. If 
logic and presentation should be kept separate (which I strongly 
support), the coding agent could even write
<span style="font-style: italic">blah blah</span>.
Programmatically this string of code and *i* would be handled exactly 
the same.

On *i* and *em*: some have stated that *em* is semantic. That is 
debatable. With reference to speech such emphasis would be a prosodic 
feature, which should be marked with aural descriptors. With reference 
to visual text, prosodic emphasis does not necessarily need to be 
displayed. Displayed italic font is often used for technical terms, or 
foreign languages, but that does not mean such text is emphasised.
