Has a long delay (around 30 minutes for DOW) between desktop updates unless you sign up for a subscription for "Real Time" which will cost you @10.95 or more per month. So it is all about selling you something and not providing you with a fun informative or even useful widget.
The only complaint I have is that in the widget dock the icon does not update to reflect the $/% like the last version did. Mine still says 0% for the DOW. Agree that interaction with yahoo! finance page can improve.
