WO vs. .Net 3.5 LINQ

I just saw that .Net 3.5 was released last week with the LINQ  
(Language Integrated Query) technology.  How does WO stack up when  
compared to the latest from MS?

I checked the wiki and it seems there is a lack of competitive  
analysis between WO and other technologies.  Can anyone comment on  
why someone would choose WO over .Net, in light of the recent LINQ  
release?  I'm looking for technical reasons, not emotional or  
political arguments ;-)

TIA
