What are all you video fanatics' opinions on DSLR video... i've played with the function on the Canon EOS 5d mark II and was very impressed... (seeing as it is a new feature that hasnt had much work)

Do you think the option of a wide range of high quality lens's and optimal high ISO performance is anything compared to dedicated video cams?

Just interested, because to my eyes, the results are nice, and changing lens's seems a great bonus!
