Flash Vs Silverlight: A Usability Evaluation

I have recently finished a paper on the usability issues between Flash and Silverlight. Please take the time to read the paper and please post your replies on my blog.

How would you have carried out the experiments differently?
What do you think worked well? or not?
How can this paper be carried on to include other issues?
