student needing some advice

hi there.

thanks for taking the time to read this.

I am studying web development at university and am looking for some clear information on the pro's and cons of Flash CS4 compared with other multi media platforms. I have chosen MS Silverfox to compare it to as i thought it should be pretty easy but i can't find the info i need. What i need is a full list of all the features on both Flash and Silverlight, I can only find a list of the NEW features on the latest versions of each of these.

Can anyone point me i the right direction or a different forum if you think i've come to the wrong place?

Any advice would be much appreciated.
